So I posted a few days ago about my motoro's eyes being cloudy. I thought it was because of him scraping them against a rock in the tank. Well, I saw him swimming mid water about 5 minutes ago and saw this massive wound! What should I do? I did a water change yesterday, as well as adding salt, and all the water levels are ideal. Could this have been caused by the shed stinger I found in the tank, or do you think he scraped it on something? Should I add some melafix? Please Help ASAP!
