Hello. I bought this gem tang the other day for super cheap because it either has a bacterial infection or a fungus. It looked treatable so I took the fish. I’ve had it in a 20 gallon long all by itself and it hasn’t been eating. I’ve put in some Melafix and also picked up some Metroplex today. Any suggestions?
