So I was looking at my tank and noticed that my coris wrasse had a cut on his head and a cut under his fin. What I was wondering is something like this fatal or will it heal up. It looks like he just nicked himself on the rocks.
I will post tank specs if you think it's necessary.
Most coris wrasses are pretty resilient. Honestly a lot of fish are pretty resilient. I have a potters angel whose fins got ripped to shreds and about 2 weeks later he looked good as new. Just keep him fat and he will heal
