The Clown Rasbora is an active, medium-growing schooling fish endemic to Southeast Asia, known from peninsular Malaysia, Borneo and Sumatra. With deep red body coloration and distinctive black spots, this species is a popular aquarium fish that makes for a striking addition to planted or blackwater tanks. In the wild, they inhabit shallow streams and creeks with sandy substrate and soft, acidic, tannin-stained waters, usually among aquatic plants or fallen branches. A hardy and adaptable fish in the aquarium, they will do well in a variety of water conditions but will display the best coloration when kept in relatively soft water at temperatures above 78F. Like most schooling rasboras, they are best kept in groups of 10 or more and will thrive with most similarly-sized peaceful tankmates.

The Super Red Devil Tetra is a rare, recently described species known only from tributaries of the upper Rio Tapajos in Mato Grosso State, Brazil. It is one of the most sought after species currently in the hobby due to both its incredible deep red coloration and its rarity, which is due largely to the extremely remote stretches of river it inhabits in the wild. Both males and females of the species display spectacular red body and fin coloration, although males develop more vivid red and longer fins. In the aquarium, the Super Red Devil Tetra is a hardy and robust species that will do well with a variety of tankmates. For optimal display they should be kept in groups of at least 5, but larger groups tend to bring out the best coloration and behavior in both males and females.

An uncommonly imported, medium-growing characin, the Discus Tetra is named for its distinctive round body shape. This species is known from the Guyanas but an extremely similar fish from the Orinoco in Colombia and Venezuela represents either a close undescribed relative or an extension of its range. In the wild, they inhabit slow moving, warm, acidic streams but will adapt to a wide range of conditions in the aquarium. Like most of its close relatives, this is a loosely schooling species that will do best in groups of 5 or more and will get along well with most similarly sized, peaceful tankmates. With their larger adult size and hardiness, this species makes an excellent tankmate for many more peaceful South American Cichlids.

A recently described species from the Tocantins-Araguaia drainage in Eastern Brazil, the Red and Black Sailfin Pacu (Tometes siderocarajensis) inhabits rapids and fast-moving waters in the wild. A recent offering in the aquarium hobby, this large growing relative of the more well-known silver dollars and pacu develops incredible coloration, with adults exhibiting deep black throughout most of the body and fins interspersed with vivid red splotches along the body that intensify when the fish are in breeding condition. Like most of their relatives, this species is an omnivore which feeds on a substantial amount of fruits, nuts, and plant/vegetable matter in the wild and should be offered a varied diet for optimal growth and coloration. While the Red and Black Sailfin Pacu does not grow to the enormous size reached by other Pacu species, it is still a large and powerful swimmer as an adult and should be kept in an appropriately large aquarium with lots of open space and moderate to strong current.

One of the more unusual so-called “darter tetras” known to the hobby, the Neon Green Darter Characin inhabits the middle and lower Rio Negro in Brazil where it is typically found in shallow, fast-flowing streams and minor tributaries, often in clear water. Their unusual body shape is uniquely adapted for life among submerged root systems and tangles of aquatic or terrestrial vegetation in moderate to strong current. This species, the only member of its genus, is named for the brilliant iridescent green coloration it typically displays when comfortable but it is capable of a remarkable range of color change in response to both its surroundings and mood, and keeping these Characins in a planted aquarium may help them display their best colors. An agile micropredator, the Neon Green Darter Characin feeds on tiny invertebrates in the wild and will appreciate small live foods like baby brine shrimp or white worms in the aquarium. They will typically learn to feed on small frozen foods but a varied diet is best, and tankmates should be chosen with care so they don’t outcompete the darters for food. A fascinating and colorful centerpiece fish for a species or biotope themed aquarium, they are a social species and should be kept in groups.

A remarkably beautiful small tetra known only from the upper Rio Negro and Uapes in Brazil and Colombia, the Tucano or Toucan Tetra was only described as recently as 1997 and remains an uncommon import in the aquarium hobby. In the wild, this fish inhabits shallow, quiet areas of flooded forest in deeply tannin stained, highly acidic waters usually in areas of dense leaf litter substrate and overhanging driftwood or branches. With their high contrast black, gold and reddish coloration, peaceful demeanor, and schooling behavior they make a unique and striking centerpiece for a blackwater, botanical-style or aquascaped aquarium. Best kept in groups of 10 or more fish, they will get along with most other peaceful tankmates but are somewhat shy and may be bullied by larger or more boisterous fish. Aquariums which closely replicate their unique wild habitat and water chemistry will help ensure the Tucano Tetra display their best coloration and behavior.
Wild Tucano Tetras and other fish collected from the upper Rio Negro in Brazil by artisanal fish collectors help support the sustainable aquarium fishery in the region which has been the focus of Project Piaba for over 25 years.

The Rio Negro Rummynose Tetra is a species of the aquarium hobby classic and the most colorful of three species regularly traded as “Rummynose Tetra” in the hobby and trade. Found only in Brazil’s Rio Negro and its tributaries, this species displays deep vivid red coloration extending as far back as the pectoral fins in most specimens. Like the other more commonly imported species it has been popular with generations of aquarium keepers due to its high contrast coloration, peaceful nature, and active schooling behavior. Their characteristic red “nose” is a good indicator of water quality as it will be most vibrant when the fish are healthy and in warm, slightly acidic water. Best kept in groups of 10 or more fish, they make ideal inhabitants for medium to large planted tanks.
Wild Rummynose Tetras and other fish collected from the middle Rio Negro in Brazil help support the sustainable aquarium fishery in the region which has been the focus of Project Piaba for over 25 years.

A tiny, bottom dwelling species of characin found throughout the middle Amazon and its tributaries, the Black Pygmy Darter Characin makes a fascinating resident for nano or biotope themed aquariums. As their name suggests, these fish have a reduced swim bladder and spend most of their time perched on or just above the substrate, “darting” instead of actively swimming in most cases similar to a goby or blenny. In the wild they inhabit a variety of habitats but are usually found in areas with low to moderate current and prefer well oxygenated water. As a shy and relatively slow moving fish, tankmates should be chosen with caution as they can easily be outcompeted for food

A medium growing relative of the more well known Silver Dollars and Pacus, the Silver Mylossoma or Hard Belly Pacu is widespread in the Amazon and Orinoco basins where they are important food fish due to their abundance and ease of capture. They inhabit a wide range of habitat types but generally prefer relatively shallow river’s edge habitat in areas of slow to moderate flow, where they are found in large aggregations. An omnivore, their diet is similar to the much larger pacu which subside on fruits, nuts and other vegetable matter in the wild and will accept almost any food in the aquarium (although protein rich foods should be fed sparingly). Due to its hardiness, active schooling nature, and manageable adult size, the Silver Mylossoma makes an excellent tankmate for South American cichlids or predatory fish.
