Poecilocharax weitzmani, the black morpho tetra or black darter tetra, is a species of characid found in South America.[1] The fish was first discovered in 1965.[2]
Description and behavior
The black morpho tetra is a small finned fish. The fish typically reaches 40 - 50 mm in length, although they have been recorded growing as large as 4 cm.[1][3] The black morpho tetra demonstrates significant sexual dimorphism, with males growing longer and more colorful dorsal and anal fins.[4]
Unlike many other small characids, the black morpho tetra does not form schools. Males have a tendency to show territorial aggression towards one another. [3]
Aquarium trade
Black morpho tetras have successfully been kept in aquariums.[3] They prefer soft and acidic water parameters. They may have difficulty competing for food with more voracious tank mates. Although uncommon, the fish has been reported to have successfully been bred in captivity.
