My Blue Tang is sick

[Gitterdone 09]

I recentley got back in town after having someone feed my Fish and corals and my blue tang is not swiming, he is just laying on his side. There isn't any discoloration on the fish what should i do? I have checked the Ph,ammonia levels, and the nitrites.Most of the other fish in my tank are not doing well nether.
Thanks for any of the help!

My first reaction would be to do a large water change...Talk to your fish sitter and dig for info...make sure they didn't decide to clean your tank with Windex or something

I Just got done doing a major water change and quarantined the blue tang. I talked to the fish sitter about everything she did and nothing came up that would seem to do this.
Thanks for the help

Im thinking that she had lotion on her hand and did not wash before feeding the corals.
