I have a male flowerhorn which is around 12months old and recently I got a female as well like 2weeks back . Kept both of the in a same tank with a separator for 4days then removed the separator and let them stay together for like 4-5days after which both of them started fighting frequently so I got the separator installed back. Now when I observe the male anal pore seems to look bigger than before and plus his stomach has gone inside. I am really worried for him can somebody please help me on this .
