I've had my fish for a few weeks and did my first water change today. (5 gallon, filtered, heated to 78 degrees) I noticed his stomach was really bloated a few hours after the water change and hes been staying down and laying on the rocks a lot, but he gets up to swim around and get air sporadically. His scales arent pine coning, and his fins and colors still look really healthy. I think I may have overfed him a bit the past few days, I accidently gave him too many bloodworms a couple times but he gobbled it all up so fast. I gave him half a pea and I saw he pooped a little bit a few hours after he ate the pea. Should I be worried about anything else or may this just be a simple case of overeating/bloating. Should I avoid feeding him for a bit and for how long?
