Can someone please tell me what exactly is wrong with my pleco? It looks like he rammed into the glass a few times. As you can see in the pic, it’s all red and looks like it has some kind of disease or what not. I have another pleco, albino long fin with a similar issue but mainly just a red snout, seems like blood. Anyone out there have any clue as to what this is? May be an injury perhaps? Thank you.
