Yesterday I just bought three fish from a guy. Two clowns and a fire-fish that were all in the same tank for a while. He’s had the clowns for like 6 years. I was checking on them this morning with a flashlight since the lights were still off and I noticed it seemed like scales were falling off. I can only see it on the clowns since the filefish just hides. They were in a bucket yesterday for about 3 hours maybe longer since I drove 2 hours to get them. I couldn’t get good photos so I added videos.
