i have a very mean mollie/platy ( not sure which). its bitting my gouramis, and they were bitting it back. im not sure what 2 do w/them as i like all the fish and they only dislike eachother. if i was to move them to a container that my betta used 2 be in would that be ok? there is no air, but i know that they breathe air. i think i asked this question before but im not entierly positive.
