Breeding
It has not been bred in home aquariums; trade fish are wild caught or produced on farms using hormone injections. Wild fish are thought to migrate to spawn during the rainy season.
Good to know
Adults reach about 20 cm and can be boisterous and territorial, bullying small or slow fish, so keep them in a sizeable group in a large tank with plenty of caves. They will eat snails and may nip at small shrimp.
