Need some help identifying the issue with my alligator gar and possibly my pleco. He's about a year old have him trained to hand feed shrimp that's his primary diet. Always socializes at the front of the tank with me and hangs right next to me everyday at my shop In the office. He all of sudden turned white for a few days which has happened once before but this time had a film on him and his eyes and it later peeled. I did a filter clean and water change along with start right and his color came back in a few days but he won't eat and is doing nothing but sitting at the top of the tank. Here's some pics of what I think might be fungus idk??? I did an epsom salt treatment and he perked up but not for long. He's also acting as though he's trying to regurgitate. It's been a week no food. I spend everyday hanging with this fish and I know something is seriously wrong and don't want to lose him.
