Feeding regime[edit]

Feed once or twice a day.

Environment specifics[edit]

Not fussy about tank set up, originates from small ponds that are low in oxygen and have little current, but this fish is flexible towards it's environment.


Generally peaceful but can be boisterous.


More Loach-like in appearance than catfish, this fish is mottled grey in colour and can be mistaken for the similar Megalechis thoracata. The difference being the presence of a conspicuous dark vertical band in the caudal fin in the M.picta.
