I have had a yellow wrasse now for about a year in my 125. Today I noticed he has a red vien looking mark on the inside of him...You can see it from one side but not from the other. I do know he get carred away in getting in the flow of the pumps and will just zoom from one end of the tank to the other so I am wondering if fish get bruised or break blookd viens. All of my water parameters are good. I have a hint of trates but nothing other than that. PH at 8.2 and temp at 80. Anyone have any ideas? Its just weird you can see it from one side of the fish but not the other.
Thanks
