I'm very lucky I got my fish from a breeder and not a pet store. The minute I notice a change in my fish I was able to email her pictures and a video. She thinks he has a bad aeromonas infection on his caudal fin. And it's all my fault I forgot to change the carbon and rinse my media on my one filter last week when I did my tank cleaning. Tomorrow I have to run out and buy some triple sulfa and a large air stone to get more aeration in there (just have a bubble wand right now). I also need to add epsom salt and baking soda to the tank after a partial water change. And put my heater in there to raise the temp up a bit. The breeder (East Cost Ranchu) is so knowledgeable and sent me very detailed instructions.
I am hoping he will be ok, my poor little Chubs Fishkin (cleo his buddy is perfectly fine):
