I was given a gorgeous red crowntail that belonged to a friend of mine. Her stomach was swollen so I tried fasting her for a few days and started her on a good verryied died with frozen foods amongst soaked pellets, flakes, etc. Nothing. So I fasted her again and I gave her a quarter of a skinned pea and after a day still nothing. The parameters are good and she’s in a heated planted tank with a filter(80°) I’m not sure what steps to take to help her. More pea? Meds?
