Hey all, picked up a new radiant wrasse on Saturday. The past 2 days he's been swimming around doing fine in the qt tank. Today I noticed he was kind of sluggish. Upon closer inspection I saw what looks like missing tissue around his mouth. Not sure what would cause this. I have a sand box with fine Fiji pink sand in it in his qt tank. He seems to burrow in it with no trouble. Ammonia had spiked a little this morning (~0.50) so I did a quick 50% water change (after I noticed the problem). All other parameters were good. He still seems to have some fight in him but he isn't eating much. anyone know if this is something he can recover from?
