Hello my name is Laurie and I am new to this site. I have an established 40 gallon tank with a Molly fish that's Junior age. My Molly (after being bullied by more aggressive and larger Mollies that are now removed) all of a sudden his back is curved. I believe it's a genetic disease because it's mother had the same problem. Does anyone have any advice or help that you can give me? From what I have read on the Internet, it's either genetic or TB. I really love this fish, and I've had it since it was born. So, the situation really bothers me!! Advice?
