I have a clown tang In my tank for about 2 weeks now. When I first go him, he was eating flakes and pellets with no problem. I’ll put a strip of nori in the tank every night and in the morning it’s gone but not sure if it dissolves, the other fish eat it (a pair of clowns and a royal gramma) are the only other fish in the tank, or the snails. Anyway, the other day I was in the tank and the water felt cold, I checked the temp and sat that the power cord to the inkbird was unplugged, hence the reason the alarm didn’t go off. The tank water was down to 71° when I normally kept it at 79°. Could the temp swing stress him out? I brought the tank back up to temp over the course of 8 hrs. A visual inspection of the tang doesn’t show any signs of ick or any other diseases. Unfortunatly, I don’t have a Qt tank to put him in. All other fish are doing well.
