i don't want firemouths, they don't act like oscars
im looking for fish that have a personality kinda like an oscar
why not just get an oscar then? if you just have the one then im sure youd be fine so long as you dont have many decorations in there so they have room to swim, ive seen people keep 2 oscars together in a 55 and the seemed happy, just be weary of your heater and maybe even your tank being broken, oscars startle easily and when they do they dart into things and swim frantically, could cause damage. but dont think theres any major problems with keeping one with another fish so long as the other fish isnt as big as the oscar.
