I’m worried about my red toothed trigger fish. I’ve had it for 2 years and he’s been doing great, very active and fun to watch. Around 4 days ago I noticed he wasn’t swimming around as much and was hiding at the back of the tank wedged in between the tank and the UV sterilizer. He hasn’t been coming out for feeding at all either. This just happened suddenly which I find weird. I’ve changed nothing in the tank and all the other fish are fine. Does anyone know what could be going on? I tried dropping food right over top of him but he doesn’t seem interested. He really looks like he’ll die soon. Is this normal for a healthy fish to just get sick like this? Any info would be great, thanks! Here’s a pic of him, it’s kind of hard to see.
