Yeah I'de personally drop it down to 76-78 and see if it helps. amazing how a few degrees sometimes does it. it also may be why even w/ sufficient filtration/water movement he's still gasping warmer the water the less o2 it holds but if you drop it too low they get digestion issues... you'de think critters from the wild wouldn't be so darn touchy.. but sometimes they are!
