Naso Tang - ID Problem

[blenny90]

These pics are the best I can get until my son comes home to get them with the better camera. We have had this juvenile blonde naso tang in quarantine for about 4 weeks now. Originally he was with a Powder Brown and a juvenile blue tang and some lyre tail anthias who have died. Live and learn - our mistake was mixing fish in quarantine from different suppliers.

The fish looked healthy when they arrived - developed ich and we treated with paraguard. This seemed to control the ich and then the ich blossomed. The other fish died rather quickly even though they were eating well. This naso is the only one that has survived. Deciding that it was no longer ich, we treated with Melafix for about a week. Stopped that treatment, did a 50% water change and have been treating with Formalin 3 for 6 days. The fish is eating well, but something is still definitely wrong.

Any thoughts, suggestions? Could this be velvet?

He definitely has ich or velvet. Doesn't really matter, treatment is the same. Pictures are not that good, hard to tell what it is.You might try copper, and furan2 to treat secondary bacterial infection.

Do you use the copper and furan 2 at the same time?

Looks like velvet. See if you can remove him to a sick tank. You can use both at the same time. But I would treat for the velvet first, if he develops a bacterial infection then treat with antibiotics. Give fish a fresh water dip in temp and PH corrected water for five minutes. You can also set the salinity in the sick tank down to 1.015. Velvet has thar powdery look while ich looks like salt grains. At least 14 days in sick tank.
