If i find wolf fish or chaca chaca or dwarf snakefish I will take one of them. However, the chance of finding one of these is very small. But i am still thinking about the pacus . Are they growing fast or slow? When they reach a size too big for my aquarium i will find then another home or maybe i will get bigger tank. Maybe it will be catastrophic if i take them but if i don't find anything of the other species i will take them.
