keep these catfish in small groups of four to six
specimens, assuming that they are available in these

are quite happy to shoal with other members of the

be found in very large shoals. They are ideally suited
to being kept in a community aquarium environment
with other medium to large species of fish such as
Bleeding Heart Tetras, Emperor Tetras and other catfish.

diet which they search through the substrate for.
Sinking catfish pellets, good quality flake foods,
granular foods, cultured whiteworm, earthworms, aquatic
snails which they relish and frozen foods such as
