In my 60g tank, I have had that female green mandarin for about 2.5 years now. There is plenty of food usually, no other fish ever seem aggressive towards that fish, but when I looked at the tank earlier, it looked like that.
I haven't been able to find what it is online, and I'm really worried about the fish. The only thing I see that might have caused that, maybe, would be if the fish has been stung by an anemone or some bristle worms, no?
Anyone can help me?
