Hasemania nana is a 2-inch (5 cm) schooling fish that hails from the rivers and streams of Brazil. What sets it apart from your typical South American nano tetra is its high activity level. During mealtimes, you will see them swarm together in a feeding frenzy reminiscent of their larger neighbor, the piranha.  Their bold, outgoing nature is one of the many reasons they are among the most popular fish sold at Aquarium Co-Op.

Adult males deepen into a coppery-orange color, whereas adult females and juveniles have a translucent, lemon-yellow hue. Their common name comes from the white tips on their fins, and their forked tail has a short, black stripe in the middle. Most silver tip tetras in the aquarium trade are captive-bred at fish farms, and they have developed an albino version for sale as well.

The Longfin Rosy Barb, is a long finned morph of the Rosy Barb which has a wide range throughout India, Nepal, Bangladesh and Pakistan. Because of this distribution, there is considerable variation in color and body size of Rosy barbs. For example, some populations may exhibit scales with higher reflectance (shiny) than others. Many of the Rosy barbs available within the aquarium trade are commerically produced however, though this variation can still be found within aquaculture. Rosy barbs typically exhibit sexual dimorphism – males possess the characteristic “rosy” red color in which their name is derived, while females don’t have this coloration and are rather a pale-yellow color.

The Golden Wonder Killifish, also known as the Malabar Killifish or Striped Panchax, is a very colorful, relatively undemanding fish that has become incredibly popular among aquarists over the past few years.  Originally a gray-green, striped fish in its native India and Sri Lanka, this fish has been selectively cultivated to develop an incredible iridescent gold and blue-green coloration across most of its body.  While some killifish have a reputation for being difficult to keep, the Golden Wonder Killifish is highly adaptable and makes a great addition to many aquariums.

Killifish typically occupy the top level of the water column, although they can often be seen swimming and feeding in the middle and bottom levels as well.  They are also not afraid to jump, so they must be kept in an aquarium with either a lid/hood/canopy or at least a significantly lowered water level.  They will not eat or bother plants, but they are fairly voracious predators of dwarf shrimp and even small fish such as microrasboras and very small danios or tetras.  As with most predatory fish, the Golden Wonder Killifish will eat any animal that will fit in its mouth. Still, there are several species of fish and some invertebrates that make for suitable tankmates.  Rams or other dwarf cichlids, larger tetras, Banjo Catfish, Otocinclus, and most Corydoras Catfish are suitable tankmates to Golden Wonder Killifish.  Snails are also safe, and large, peaceful crustaceans such as Vampire Shrimp could live peacefully with this fish as well.  Golden Wonder Killifish are best kept in small groups.

The cherry barb is a freshwater fish of the Cyprinidae family. The fish is small, bright red, and has a distinctive lateral stripe that spans the length of the body.

If you're looking to maximize the color-to-size ratio of your fish, you'll be hard pressed to beat Cherry Barbs (Puntius titteya). Males are an electric red color that can be spotted from across the room, despite their average size of 1-1.5". Females sport golden-orange bodies and may be required for males to show their full colors. 

Cherry Barbs like calm, planted tanks. Tankmates include other small cyprinids, tetras, livebearers, and most peaceful fish. They are extremely tolerant of water chemistry - ideal for the beginner aquarium.

The Glowlight Rasbora (Trigonostigma hengeli), also known as the Lambchop Rasbora, is a strikingly beautiful nano fish that is very popular among aquarists due to its schooling behavior, peaceful disposition, and very small size.  This schooling fish can be the highlight in any peaceful community aquarium and it is a particular standout in the planted aquarium with dark substrate.

The Glowlight Rasbora typically occupies the top and middle level of the water column, although it can often be seen swimming and feeding in the middle and bottom levels as well.  It is safe with other peaceful, small fish.  This small rasbora can be housed with adult dwarf shrimp, although it might prey on shrimp fry.  Larger, peaceful invertebrates can also make good tankmates.  The Glowlight Rasbora must be kept in schools of 6 or more, although larger schools are more ideal. The schooling behavior of a large group of this fish is fascinating.  Its natural habitat typically has slow water flow and contains acidic water rich in tannins and leaf litter.  It requires very clean water to thrive and it will display optimal coloration and health in a planted aquarium with dark substrate, especially where floating plants are present.  This fish is exceptionally adaptable for a microrasbora.
