Fish Disease Information and Treatment

  When it comes to receiving discus fish that are laying down from transport, it is crucial to follow the proper steps to ensure their well-being. Discus fish are known for their vibrant colors and unique patterns, making them a popular choice for aquarium enthusiasts. Here is the ultimate guide to receiving discus laying down from transport. 1. Acclimation Process Upon receiving your discus fish, it is important to acclimate them to their new environment. Float the sealed bag in the aquarium for about 15-20 minutes to allow the water temperature to equalize. This will help reduce stress on the fish during the transition unless the bag is inflat at arrival then will require to acclimate with difference  technique.  Some case, the bag is inflat at arrival, you should prepare a container which has an airstone then open the bag => dump the water and fish out to a container => use an air tubing to acclimate. Depending on water parameter between your tank and supplier tank, you should slow acclimate or let water freely flow. At texas Aqua, our PH normally around 7.2-7.6 and tds around 300-350ppm, We know the water parameter from breeder so we nomally dont worry too much about those number, we just prepare 1/4 water on our tank matching with the bag then cut and dump. We let water filling in and draining out as the same time. We never have any issue with this technique  2. Water Quality Check Before releasing the discus fish into the aquarium, make sure to check the water quality parameters such as temperature, pH level, and ammonia levels. Discus fish are sensitive to changes in water conditions, so it is essential to maintain a stable and clean environment for them. 3. Quarantine Period It is recommended to quarantine the new discus fish for a period of 2-4 weeks to monitor their health and prevent the spread of any potential diseases to other fish in the aquarium. During this time, observe the discus for any signs of illness or stress. If fish laying down right after you release them from the bag, this is normal. Please do not panic, Just lower the water down to 1 inch above the upper fin in normal standing position. add airstone, add header and keep it at 84-86F. Add some aquarium salt and add metrodinazole 500mg/10 gallon, do not turn the light on nor trying to feed the fish. Just leave them alone. After 10 hours, add another dose of metrodinazole then do water change after 24h then add metro and salt again. Remember do not raise water until fish swimming back to normal.  4. Feeding Schedule Establish a regular feeding schedule for the discus fish, offering them a varied diet of high-quality flakes, pellets, and frozen foods. It is important to provide a balanced diet to ensure their nutritional needs are met and to promote healthy growth and vibrant colors. If you use RO water, you should always remineral such as vitamin, Ca,Mg...to ensure it is enough so then can growth as fish require not just those in food. They will absorb it from water as well. 5. Tank Environment Create a suitable and stable tank environment for the discus fish with plenty of hiding spots, plants, and open swimming areas. Discus fish prefer warm water temperatures between 82-86°F and soft, slightly acidic water conditions. Maintain good water circulation and filtration to keep the tank clean. By following these steps, you can successfully dealing with discus fish laying down from transport and provide them with a healthy and thriving environment in your aquarium.

Discus fish, with their vibrant colors and unique shape, are a popular choice among aquarium enthusiasts. However, these beautiful creatures are also known for their susceptibility to various diseases. One such disease that can severely affect the health of your discus fish is a bacteria infection caused by discus flukes. This article aims to provide you with comprehensive information on how to identify, prevent, and treat discus fluke infections in your beloved aquatic pets.What is Discus Flukes ?Discus flukes are parasitic flatworms that attach themselves to the gills, skin or fins of the discus fish. They feed on the blood and body fluids of the fish, leading to severe discomfort and health issues. The most common types of flukes that affect discus fish are Dactylogyrus (gill flukes) and Gyrodactylus (skin flukes).These parasites can cause a range of symptoms in your discus fish including lethargy, loss of appetite, rapid breathing, excessive mucus production on the skin or gills, and visible spots or worms on the body or gills. If left untreated, a severe infestation can lead to death.How To Identifying Discus Fluke Infections?The first step towards treating any disease is accurate identification. Discus fluke infections often manifest as unusual behavior in your discus fish. You may notice your sick discus rubbing against objects in the tank or displaying erratic swimming patterns – these are signs that they may be trying to dislodge the parasites.Other symptoms include rapid breathing due to gill damage caused by the flukes and a decrease in appetite as the infection progresses. In advanced stages of infection, you might notice visible worms on your discus' body or around their gills.How To Preventing Discus Fluke Infections? Prevention is always better than cure. To prevent discus flukes, maintain optimal water conditions in your aquarium. Regular water changes, proper filtration, and avoiding overcrowding can significantly reduce the risk of a fluke outbreak.Quarantine new fish before introducing them to your main tank to ensure they are not carrying any parasites. Regularly inspect your discus fish for any signs of illness and act promptly if you notice anything unusual.How To Treat Discus Fluke Infections ? If you suspect your discus fish has a fluke infection, it's essential to act quickly. The first step is to confirm the diagnosis. This can be done by taking a skin or gill scrape and examining it under a microscope for the presence of flukes.Once confirmed, there are several treatment options available:1. Medication: Anti-parasitic medications such as Praziquantel(500mg/10 gallons) or Flubendazole(500mg/10 gallons) are effective in treating discus flukes. These medications can be added directly to the aquarium water.2. Salt Baths: A short-term salt bath can help dislodge the parasites from the fish's body. However, this should be done with caution as discus fish are sensitive to changes in water conditions.3. Formalin bath or soak, we only soak, not bath: Formalin(3.5 ml / 20 gallons for soaking technique). This is a powerful anti-parasitic agent that can effectively kill flukes. However, it's potent and should be used with care due to it is a very strong medication which will kill your fish if you using it wrong.4. Potassium Permanganate: This chemical can also be used to treat discus flukes but should be used cautiously due to its strong oxidizing properties.Remember that while treating your sick discus, it's crucial to maintain optimal water conditions in your tank and provide them with a balanced diet to boost their immune system.Discus flukes are a common issue that many aquarists face but with early detection and appropriate treatment, they can be effectively managed.

This disease is caused by a bacteria infection and can be fatal if not treated promptly and effectively. In this blog post, we will discuss how to identify, prevent, and treat discus plague.Many Newbie in keeping discus can not identify any sign when discus fish get an issue. So today we will get into the definition of discus Plague.What is Discus Plague?Discus plague is a term used to describe a severe bacterial infection that affects discus fish. This disease is often characterized by rapid onset and progression, with affected fish showing signs of lethargy, loss of appetite, color fading, and rapid breathing. If left untreated, the discus plague can lead to high mortality rates within your aquarium.The bacteria responsible for this disease are usually present in most aquariums but only cause problems when the fish's immune system is compromised due to stress or poor water conditions. Cross contamination from an infected tank or equipment can also lead to an outbreak of this disease.Identifying Discus Fish Bacteria InfectionEarly detection of discus plague is crucial as it significantly increases the chances of successful treatment. The first signs of a bacteria infection in your discus fish may include behavioral changes such as reduced activity levels or loss of appetite.Physical symptoms may include color fading or darkening, clamped fins (fins held close to the body), rapid breathing or gasping at the surface for air. In advanced stages of the disease, you may notice ulcers or sores on the body of your fish.Preventing Discus PlaguePrevention is always better than cure when it comes to dealing with diseases like discus plague.

Consult with a vet or an experienced aquarist for advice on the best antibiotics for treating discus plague if you do not want to use bactocide 1 and bactocide 2. Commonly used antibiotics include kanamycin, metrodinazol (only active for 8hours after contact with water, 500mg/5-10 gallons water), tetracycline(work less for some type of bacteria and water look nasty, we don't use this much because less effective than other medication), japaniese tetra(soaking for 2 days. This is last step before move back to main tank) and salt(we use natural solar salt from homdepot, 1 table spoons/1-2 gallons). Remember keeping water at 84F, change all water every 24 hours or as soon as it look dirty before 24 hours and reapply medication. add an airstone to increase oxygen.3. Supportive Care: Provide supportive care by maintaining optimal water conditions in the quarantine tank and feeding a high-quality diet.4.

1. Identify, symptom and the reason to cause of bulging eyes Pop-eye is not a specific discus disease itself but describes a condition and can be a symptom of an illness or infection in fish. In medical term, it also known as exophthalmia. This is a condition where the eye of the fish is swollen and protrudes abnormally from its socket due to various underlying diseases. This issue affect on single eye or both eyes. This illness cause by a bacteria named Steptococcus.   Note: The picture above was used with permission from " Handbook of Fish Diseases" by TFH Publications, Inc. It also may be caused by a variety of organisms, including bacteria, fungi, and parasites. If the fish suffers from both pop-eye and dropsy (edema of the belly), the prognosis is bleak. Internal problems, such as kidney failure or a metabolic issue can result in fluid build-up, making it extremely hard to treat your fish. Poor water conditions can also contribute to pop-eye and fish that are sensitive like discus will be affected faster than other hardy fish. In late stages the spine can curve. Often times they stay at the back of the tank.  2. How to treat Pop-eye on discus fish.  Please look for any sign, symptom to identify the problem before treatment. This step is very important as it will give you more chance to success treating the illness fish. Treatment for pop-eye will depend upon the underlying cause. The treatment step bellow is base on our experience and apply for fish from Texas Aquatic only. We are not guaranty or using this statement to replace for any doctor advises. You make your own decision on how you want to treat but these step worked perfectly for us after many years in keeping and breeding fish specially with discus fish. a. If pop-eye caused by poor water quality, you must do a heavy water change. This sometime will fix the problem. b. If the pop-eye caused by bacteria then please follow these steps: - Lower temperature and keep between 80 to 82 degrees F. - Use Epsom salt, 1 to 2 tablespoons for every 10 gallons aquarium water. - Use antibiotic with an internal affect such as Neomycin, Kanamycin, and Erythromycin. 500mg/10 gallons aquarium water. These are some example of medication that work well for this issue. You can use as directed, if improvement is noted, please continue through a second course of treatments. - Do not change water until day 5 in the treatment, before the third does of antibiotic. New water helps the bacteria more than it helps the fish. If water is too dirty, just change 10-20% then reapply second and keep continue the treatment. After day 4, change 50-70% of water. - Lowering PH will inhibit bacteria(6.0 range), this also prevent any ammonia becoming toxic if the bio filter is affected, which means less stress for fish. - If the fish start eating, a medication such as Discomed may be added to the food.

The Altum Angel is a wild fish from the rivers of Colombia, South America. This fish is really rare in the wild compared to other freshwater angelfish, first identified by Dr. Axelrod as Pterophyllum scalare altum. This species was later re-identified as Pterophyllum altum. The Altum Angelfish can be identified by the silver vertical brown stripes on the body. The fins are slender and long, extending most of the body of the fish. This is the most beautiful of the angelfish.Altum Angel needs a glass tank with a minimum capacity of 30 gallons of water, with soft, acidic water. Rocks and driftwood can be added to the tank, but need to leave space for the fish to swim freely. When raising Altum Angelfish, you need to feed them a full range of different foods including plants, vegetables, and meats.- How to identify the Egyptian Altum-Peruvian Altum and the 3 stripes: + Egyptian angelfish- The most special feature is the Egyptian angelfish with a size of up to 6 inches, the largest of the angelfish species.- The fins are stretched, the longitudinal stripes are bold and close together (closeness between the lines), the size of the black bars is also uniform and larger than other angelfish. (This point is not very accurate, when the fish reaches a large size, you can see it quite more accurate) - Standing fin close to 90 Degree- The mouth of the Egyptian angelfish has a clear broken point- The color of Egyptian angelfish if about five colors, the end of the fin and the tail fin of the Egyptian Altum is red + Peruvian angelfish- Although the fins are tight but still not as tight as the Egyptian angelfish, the stripes are also bold but not close together (tightness between the lines) like the Egyptian altum- The space between the two main stripes never goes straight down to the abdomen (When young, it can be pulled down to the abdomen, but as it gets older, it becomes more blurred and only extends less than 1/3 from the dorsal fin to the middle near the middle of the body. - The biggest difference is that there are dots and spots on the body of the Peruvian angelfish + Three-striped angelfish -  While the mouth of the Egyptian angelfish has a broken point, then the 3-stripes has only a slight fracture- The size of the three-stripe angelfish is up to 3 inches only, not up to 15cm like the Egyptian Altum- The 3-stripes angelfish color shines a lot of blue, and the Egyptian Altum has many colors such as five colors, and red tail fins- The selling price of the Egyptian angelfish is about 10-15 times more expensive than the 3-stripes angelfish

Discus is considered by many aquarists to be the most amazing freshwater fish, It is the "king of the aquarium" by their mystery look and the beautiful appearance as well as their behavior. . Discus is considered by many aquarists as the most amazing freshwater fish Where are discus come from: Amazonian Basin, Brazil South America, now widely farmed in Asia. Body shape The size is about 8 inches max under proper care and full growth, the height is equal to the length, making the body shaped like a round disk. The mouth is small, the eyes are large and often red or yellow. Males are usually larger than females. Characteristics Fish need a large space to swim, suitable for quiet places, or startled when they see people. Discus likes to live where clean water has a low pH of 5 - 7, the temperature is from 82-84 o F. Discus fish is a species that love eating worms, lentils, heart, liver, ground beef... or industrial foods with a protein content higher than 30%. Breeding Male fish: large shape, slightly hunched head, saggy ventral fin, under the abdomen the concave fin area looks very clear, more aggressive than female fish. Females: usually smaller than males with short protruding genital spines, divided into 2 pointed lobes and slightly curved back. Fish can spawn after 12-18 months of age. When they mature, they will pair up with each other, separate the group and swim to a corner. It is difficult for discus to breed artificially, artificial spawning tanks should have a slightly acidic pH (PH=5.5-6). The mating phase occurs during the spawning period, the pair of fish will separate themselves in a corner of the tank, using their mouth to clean the place where they will spawn. These fish often stay close to their mouths, wag their tails, chase each other, and scare away other fish that come near them. Then they swim in pairs, entwined with each other. A few days before spawning, the fish has a shivering phenomenon, shaking the whole body, folding the fins, sometimes standing still in place, rarely catching prey. When the fish is born, the head is lowered to 45 degrees, at this time the genital spines are clearly visible, the color is very bright. The female fish lays eggs vertically on the substrate, from the bottom up, the male fish also follows that route to spread sperm to fertilize the eggs. The number of eggs laid by the female participating in the first spawning is usually 70-80 to 150, sometimes more. Fertilized eggs are transparent. Unfertilized eggs are cloudy. After 24 hours, the fertilized egg turns greyish white. At 86o F the eggs hatch within 55-57 hours. During this time, the male and female fish take turns moving pectoral fins to fanning water so the eggs to get enough ventilation. Egg hatching rate: 60-90%. Should give the fish to spawn in a quiet place (cage, cover the fish tank). Breeding fry: After the eggs hatch into fry, the parents take the fry to another location. The fry cling to the wall of the tank or a substrate. Juveniles cannot swim yet and live off of reserves in the yolk sac below the abdomen. Any fish that is dropped will be brought back by the parents. After 60 hours, the fry can swim around the parents. The fry live by eating slime from the parents' bodies for 12-15 days. After that, the fry begin to eat small organisms in the water. About 18 days, the fry can eat artificial food. After 21 days they can find food on their own. Newly hatched fish is very small; after 1 week the fish is 1/8 of an inch long. About 2 weeks old, fish 1/4 inch long, straight striped body, gray-brown eyes. At 18 days, the fish is 1/2 inch long, the dorsal and pelvic fins are black and colored. About 5-6 weeks, the fish is about 1 inch long, shaped like an adult fish, but the color is unknown. After 3 months, the fish is 2.5 inch long and the color is clear, but it is not until the 5-6th month that the fish has the colorful color of the adult fish. In the first time, from day 7, should feed fry with live brine shrimp several times a day, avoid overfeeding. Food should be evenly distributed throughout the tank, avoiding large fish competing for food. Then until 2 and a half months, fish should be fed water lice (Daphnia), brine shrimp. Fish 3-4 months old feed more larvae, blood worm...etc. For the first few weeks, the water temperature should be kept at 84-86° F. Light for about 18 hours is recommended. But don't use too bright light. Translated by Son Nguyen

Flowerhorn fish is a fish obtained through the re-creation method of aquarium artisans, but there is no such fish in nature. In fact, they are hybrids from many different fish species sharing a very diverse family of tilapia, which has more than 400 species. The first Flowerhorn appeared in aquariums in Malaysia. Flowerhorn fish often suffer from some of the following diseases: 1. Hole on the head The disease is caused by a single-celled parasite called Hexamita. The cause of the disease is poor water quality and improper fish care. In addition, it can also be due to improper diet.The disease usually manifests as small blisters or holes appearing on the head of the fish. These pimples are usually white and have mucus around them. When sick, fish is often accompanied with long white string. Treatment: This disease can be spread very easy, so it is important to isolate the sick fish as soon as it is detected. We put in the isolation tank a drug called Metronidazole (250mg for 10 gallon of water). Continue to add the drug to the tank with the same dosage as above for 10 days. During this time only change about 20-30% water between each treatment. It is possible that during treatment the fish will stop eating. If this disease is detected in time, the success rate of treatment is very high. 2. Inflammatory skin disease The disease is caused by bacteria Aeromonas, Pseudomonas and Vbrio. It can also be caused by a parasite or fungus. When sick, the external skin of flowerhorn fish will appear red and swollen patches that are getting bigger and bigger, whole body itching. So fish often rub their body against the bottom of the tank or any object in the tank. How to cure: When the fish shows the above symptoms, we must first conduct regular water changes. Note: Do not put in the aquarium any object with sharp, sharp edges because it will make the fish more scratched when rubbed. Add antibacterial drugs such as Methylene blue (5ml/10 gallon of water). Give the medicine once every other days for 10 days and change about 50% of the water before putting the medicine in. 3. Fish disease loss of balance When suffering from this disease, the fish suddenly loses its balance and lies on its side, the body is bent, indicating that there is an injury in the spine. Dermatitis at this time also appears on the fish. Therefore, the cause of the disease is thought to be damage to the muscles or vital areas of the body, genetic defects or malnutrition. How to cure: In fact, there is currently no effective treatment for this disease on the market. However, it can also be treated by lowering water level and changing the water every day, feeding the fish with your hands and helping the fish to return to a balanced position when the fish leans away. With this method, it takes a lot of time to be effective 4. Piercing disease Classified as nutritional and parasitic diseases, cichlids often suffer from this disease. When the fish is infected with this disease, its body, especially the head, often appears small holes, the fish has no appetite, the abdomen is sunken in, white string in fish waste, if not treated promptly, these holes will penetrate through the epidermis or abdomen, causing other diseases, leading to fish death. Fish with perforated head disease due to nutrition, the body color also gradually turns to a gloomy pale black color, at this time, Vitamin A, D3 can be added to the food. If it is infected, it must be disinfected. If the fish is sick due to parasites, in addition to the symptoms of a punctured head, the intestines and abdomen of the fish are also infected, accompanied by the phenomenon of floating white particles. This phenomenon may also be due to the deterioration of the water source, the change in water temperature, the density of rearing and spawning is too thick, the nutrition and oxygen are not enough to supply the fish. At this time, medicine must be used to treat the fish. 5. White spot disease Symptoms of the disease are white spots or a cluster of small yellow spots on the outside of the body. When fish are infected with white spot disease, they will be itchy and constantly rub themselves around the tank, so on their bodies appear small white cysts, this disease is easy to arise when the temperature and pH change. sudden change. White spot treatment: Mix Epsom salt into the water about 1 teaspoon for every 10-20 gallons, increase the water temperature to about 86 F or more, adding some metronidazole(500 mg / 20 gallon water) can help treating this problem as well. Or you can bathe the fish with salty water for 10 second and every day for 3-5 days. You can also use methylene blue for every other day for 5-10 days until the white spot disappear. This is very simple disease to treat for flower horn. normally just need increase water temperature and bath fish with Salt.   Translated by Son Nguyen
