This species was formerly known as Anostomus trimaculatus and this name is still used in much of the available literature. It is now invalid, however. The genus Pseudanos contains 3 other known species, P. gracilis, P. irinae and the recently described P. winterbottomi. Care for these species is as for P. trimaculatus....

Maintenance

A biotope aquarium would consist of a sandy substrate with driftwood roots and branches. Algal growth should not be discouraged. If kept in a planted aquarium, any soft-leaved varieties will be eaten and even the tougher species will be picked at. Water flow should be quite strong. A well-fitting cover is essential as Pseudanos are excellent jumpers.

Behaviour and compatibility

Aggressive towards its own kind when kept in small numbers, it can be maintained in groups of 6 fish or more in larger aquaria. Otherwise, keep as a single specimen in a community of medium to large fish. Suitable choices include larger characins (but not other Anostomids), Loricariids, Doradids, peaceful Cichlids, knifefish, Corydoras etc. It may nip at long-finned fish, especially slow-moving species.

Sexual dimorphism

Unknown.

Reproduction

Not reported in aquaria.
