So i bought 2 gourami a few days ago. 1 male and 1 female. They have been doing fine together. The male gets just a bit aggressive when food is put in but otherwise they are fine together. Someone owner surrendered a male gourami at the fish store i go to. Some people online say 2 female for every male or that males can live together. I decided to take him home today. Well my male is chasing the new male and nipping at him a lot. Should i wait to see if maybe they might get over it in a day or just go return the new male back to the shop tomorrow? I might not have time tomorrow so should i go ahead and seperate them?
