I noticed last night that something is wrong with one of my mono's mouth. His jaw seems to be messed up. I don't know if it is broken, injured or what's going on. I tried the best that I could to take some pics but I couldn't really get a good shot of it. Is this something that can heal or is this fish going to be deformed for life? I don't know how this could have happened. I would really appreciate any feedback from you guys. Thanks
