Hi, I’ve noticed my purple firefish being lethargic as of this morning staying on the sand instead of being in the middle swimming into his cave and bonding with his best friend (regal tang). I’ve tried peas with the shells removed incase it was his swim bladder as he was tilting a big but that has settled for now. He didn’t take any food this morning or afternoon when I fed him either, he’s trying his best to swim around but is only doing it for short periods of time. Can anyone diagnose what it is? He has a white/red wound behind his left pectoral fin so he either hurt himself going into his cave too hard or he’s been attacked. His tank mates are a clownfish, regal tang and anthias.
