I have one blue damsel in a 55 gal. He's been in it for about 3-4 months, and been doing well. However for the last 2 days has been staying in the corner and apperas to be gasping. his eyes have swelled and retracted again, but he has a small bump over one of his eyes and is still cornering, and gasping. what's wrong with him and what can i do? the tank is a 55 with DSB, and CPR bakpak, it's got 1 NO 40w light, and the water checks out ok. thanks
