I need help, I don't know what else to do. I got a blonde naso and blue regal tang nine days ago. We were told we had to buy both together and introduce them to the tank at the same time. So thats what we did at first they were doing ok then I noticed white salt like things all over the blue regal the blonde naso was just breathing hard no spots. Long story short, it turns out they both have ich. So we the local fish store talked us into buying a red sea wrasse, we were told it will eat the parsites. Which the wrasse does but it wasn't really curing the ich. It just helped relieve some of the symptoms. So next, last night we did a fresh water dip on both fish. I know that doesn't cure ich either....but I heard it would help and hopefully the fish would over come this on their own. We don't have a QT tank, I know now this was a big mistake also. I didn't think the blue regal was going to make it last night after putting him back in the tank he sunk to the bottom and got real stiff, he was breathing hard and did'nt move all night. This moring when I got up he was swimming around having a good ol' time. The blonde naso, just lays behind the live rock and breathes hard, he won't swim around anymore, and worst of all he hasn't eaten in 4 days. I don't think the fresh water dip did much for him he has been acting like this for four days now. How long can he live without eating? AHHHH I know he's suffering, and the fresh water dip probally just caused more stress. We checked all the levels and the fish store rechecked them for us. Evrything was ok except nitrates were slightly elevated. We are even soaking the food in garlic. The only thing left is copper treatment or hyposalinity treatment. Is it even worth it? I know we would defiently have to set up a QT tank then. We have like rock, inverts and coral. I just need advice, should I just leave him alone? He won't eat the garlic doesn't help. Whats next? I just don't want to let him die if there is something I can do.
