    1. Widely deemed to be highly aggressive to other fish,however many live very peacefully with community fish,all have distinct personalities,some very lively,some couch potatoes! They really get to know and recognize owner. The “puffing”behavior is usually only exhibited when the fish is in danger or stressed,it is not healthy to try to elicit this behavior on purpose,occasionally they seem to puff for no good reason. It is dangerous for the fish to puff up with air and so it should be caught in a tub of water rather than netted.


Biotope:Inhabits large rivers and lakes


There is no known way to identify the sex of this fish and captive breeding has not been achieved.
