My 6 line is looking pretty wide and bulgy lately and I wanted to get some opinion to what might be going on or how to treat. It is swimming fine and eating plenty (maybe too much) and thought she may be constipated. I am wondering if anyone has ever treated a constipated fish in their reef tank, or maybe I am misdiagnosing. I have read that peas can be used for freshwater fish, should I try that?
