My flame angel who has been a model citizen since introduction 6 months ago has started nipping at my 6" crocea causing him to stay partially closed. I'm sure this will eventually kill him. I'm sure others have run into a similar problem. Maybe someone has come up with a solution other than removing either the angel or the clam. I cut back on feedings recently to help battle a cyano problem and I believe this put the flame in search of sustenance. As the cyano recedes I will step up feedings. Do you think this will solve the problem or is it a case of once a nipper always a nipper.
