i have what is supposed to be a breeding pair of gouramis but, the male is super aggresive and once i put im in with the female he began to nip at her tale as if he wanted to mate with her, but there is no bubble nest build and she isn't even the slightest bit intrested. I hade to seperate the pair because he was going to kill her be tairing her tail appart. what do I do. P.S. they are in a 33 long heavly planted.
