I have an extremely fat Tomatoe Clown. Some have said maybe it’s constipated? I. Going to isolate it with a small quarantine and try a peeled frozen pea to see if that works...it has been this way for about 3weeks or so. First I thought it was pregnant...but it’s been too long. Any other ideas I would appreciate the info. Swims well, is the smaller one of 4. Help please
