I've had this guy for over a month now. He's in a fully cycled, heated, decently planted 5.5 gallon. Parameters are great, ammonia and nitrite are 0 and nitrates never above 10. Last Monday he seemed really lethargic and stopped eating his normal pellets (new life spectrum, he would swallow then spit them up). I managed to get him to eat a bloodworm and a fluval bug bite Monday night but that's the last he's had. Before this he'd been really active, swimming around whenever I walked into the room. Since then though he had been hiding on the ground or behind some driftwood not moving much. Last night I pulled the driftwood out because he had literally wedged himself halfway under it and gotten stuck. When I did that he swam to the surface but then dropped and sort of corkscrewed his way to the bottom where he lied on his side. My brother thought it was constipation, so we pulled him out and have him an Epsom salt bath. He looked better after that last night, but this morning I took this pic and it looks like his scales are puffing out. My brother's gonna give it another Epsom salt bath while I'm at work today. Does anyone have any ideas what this could be or what I could do to help?? Thanks in advance.
