So one of my chromis has a weird looking mark on the side of its body. I am going through the ugly phase so at first I thought he brushed up against a rock and it was just diatoms or something that rubbed off onto him but upon closer inspection, I dont think that is it.
I am wondering if it is a burn since my heater has something stuck to it about the size of the mark on the chromis. Ideas?
I have caught the chromis sleeping wedged between the heater and the glass in the morning before lights on so that is my best guess.
anything I should do to treat? Does anyone have any other thoughts?
