Blonde Naso Issues

[Shawna Solomon]

Hello,
I got a blonde naso about a month ago for my 125. He’s been acting normal and eating very well until this morning. I woke up and he was lying down on the side of the tank. I’m not noticing any ick or any type of disease but just in case I took him out and put him in QT. He’s still laying on his side and won’t eat seaweed which usually he attacks when I put in the tank. I added bacteria, parasite, and fungal medication but is there anything else I can do? I’ve had a naso before and he died within two days of being shipped to my house but I thought that was stress from being shipped. I had him in QT and my heater busted so I never found it if the treatment helped any advice would be greatly appreciated.

Also, the other fish in the main tank are doing well they are eating and swimming like normal.

Can you upload additional pics with white lighting? There is something going on there it appears.

Oh he does have some big white spots but I think they get those when they are stressed he goes through phases where he gets them I thought it was normal. But yes I’ll upload another pic.
