Hey, I'm new to this site and came here as since I can't find help from anywhere, so I hope you can help. I just recently (about 2 weeks or more ago) had to tear apart my precious tank because life hates me and cursed my tank with an ich outbreak. So now all my fish are in quarantine tanks receiving the copper treatment for 8 weeks (cringe). All my fish have been doing well until about a 2 days ago when my powder blue tang just decides that food doesnt interest him anymore. He was eating like a beast until then. He stopped around the time I started soaking the food in zoe and zoecon, and adding vitamin c to the water so the fish get everything they need without the live rock. He ate it the first night and then the next day no food interests him. The only positive outcome of this is that his color has returned brilliantly and better than before after adding the vitamins. I tried putting in algae and romaine in but he won't eat that anymore either. Is is the zoe, zoecon and vitamin c or somthin else?
