My Whitecheek/Goldrimmed Tang has something wrong with his mouth. The mouths has ragged edges. It looks like his was bitting his lips. He was much more careful than usual to nip on Nori. I started PraziPro treatment (dosing in QT) a few days ago and shortly after noticed that the tang's mouth looks damaged. Also I started using Xtreme Garlic: added a few drops to defrosted food. Wonder if garlic could've burned his mouth since he grabs it as soon as the food hit the water. Please, tell me if there is something wrong with my tang? Thank you.
