This is a very interesting tetra because it is not a schooling species and prefers to be either kept alone or as a pair. I have kept this species several times but caught it for the first time on a trip to a jungle clearwater stream.
Size: I have seen this fish grow to about 1 and 1/2 inches.
Distribution: This fish is widespread in South America.
Aggression, tankmates: This is generally a solitary species but may be kept with other species of fish from the same basic habitat.
Housing requirements. You may keep this fish in a ten gallon aquarium since it is not very active. It may eat fry as it has an unusually large mouth. Does not do well with a ph much above 6.0. It requires soft water, and enjoys hiding.
Notes: This is one of the most interesting tetras I know and even though it generally is very structurally oriented if it feels well enough it will come out to the front of the tank to gobble up food.
