Feeding A fish that likes to dig around for food, but will eat all prepared foods that find their way to the substrate. Live bloodworms or tubifex are especially relished - be careful with the tubifex. It can be difficult to feed carefully and if it starts living in the tank water conditions can quickly deteriorate. This can, at least in part, be controlled by offering tubifex in a shallow ceramic bowl.
Furniture Open spaces of substrate and rock or wood refuges slightly elevated to provide the shade these fish like to rest under in rare moments of inactivity. This species will gleefully uproot plants at the first opportunity, use plant pots or other methods of fixing plants in place.
Compatibility An ideal community tank resident, keep in shoals.
Suggested Tankmates Can be kept with most fish. More suitable for keeping with loaches than Corydoras as their larger size helps them compete better for food. Boisterous enough to be kept with more dynamic aquaria. Perfect for an Amazon river biotope.
Breeding Reported by no details survive of the account save it is supposed to spawn in a manner similar to Corydoras.
Breeding Reports There is no breeding report.
