if one is not enough, then what combination of fishes do you have in your tanks?dont have to be in one tank, but currently I have 4 tanks running,
the 1st is for my bichirs and plecos,
2nd is for oscars
3rd is for CKs
and last is for more peacefull fish like corys, and raphael cat fish,
and if I see other interesting fishes in lfs, the chances are I will get them
cheers
