Whats wrong with my fish ??

[FWC]

The tank is younger ,however its old enough

The water tested fine when it was tested a few days ago ,I'll test it again when I get home from work.

I think its a parasite of some sort ,as this morning and last night the wrasse was going to town cleaning everyone ,and this morning all the fish were out swimming around ,as opposed to yesterday ,when everyone was hiding.

Also everything does indeed look very clean ,I'm pretty anal about it looking clean. I dont let scum grow on my glass ,tubing or powerheads.
