I have a 3 to 4 inch FH that has been acting strange lately! He was eating like a pig up until a week ago and I thought he was just scared of the Jardini in his tank. He quit eating for about a week. He would take a bite or 2 every other day...maybe... Then I come home today to find a larger then pea size reddish thing comming out of its browneye. Could my fish have just been constipated? I thought it was his guts comming out but now an hour later the fish looks, eats and swims normal! Any1 ever have this concern?
