There are no known visual sexual differences between the sexes of this fish. There are no known records of this fish being bred in captivity.

Tank compatibility[edit]

Despite its size, this fish is generally peaceful towards tank mates and others of its own species. It makes a good tank mate to other Doradid catfish and semi-aggressive tank mates. Can be trusted with fish slightly smaller than itself but should not be kept with very small or delicate fish.
