Hi, so I had my longhorn cowfish so few months now and just recently, I have noticed under his mouth, his skin was being eaten away by something. I'm thinking its some type of bacterial infection. I have been feeding it some antibacterial frozen foods, it looked to have been getting better but just this morning, it started getting worse again. If anyone has experienced something like this or know what this might be, please let me know what this may be and or how to help him. Thanks
