This species is sometimes available as an aquarium fish, and has been popular in the hobby for a long time.

Because this fish is primarily nocturnal, it will retreat from brightness in the aquarium.

When larger, these fish may prey upon smaller tankmates  as these fish have relatively large mouths for their size.

This fish does well when kept in small groups when young, although as it ages, it becomes somewhat aggressive towards those of its own kind.

This fish inhabits quiet water with vegetation.

Females lay 150–200 eggs of 2 mm (0.08 in) in diameter.

This species can produce barking sounds.

They come to the surface from time to time to swallow air.

They feed on worms, crustaceans, insects, and snails.
