Dilemma

I have had my 90 gallon going since Feb. Or so this year coming right from a 55. I quarantined all new additions and three original fish were transferred. Nothing at all new added in at least three months. I have been seeing rubbing flashing from yellow wrasse for quite awhile, I can't say when I noticed first. I just shrugged it off because it was one flash I saw once in a week. Lately, for instance tonight I witnessed yellow flash half dozen times, fairy wrasse shaking head into glass repeatedly. My blenny has been staying very skinny. And I think I saw some head shaking from a clown.


Now I have not seen a single instance of white spot in 20 months or so even from the time of the 55.

All feeding is tremendous. Wrasse are so fat. Benny eats but no weight gain. LT Anthias doing okay, one new female who is the only of the darker orange variety staying skinny. RG is fat.
Running 6" protein skimmer and using home RODI.

I'm wondering if I have a build up of flukes or some other non visible irritating being? Tank stats are good, temp is at 75 being it's winter. Alk is a little low at 6.4. All else is normal.
I've contemplated many times to tear down to catch all fish and set up bare tanks and perform a totally new quarantine, perhaps w/o ttm tho.
I once had a questionable bottle of prazi last year. (Seal gone upon opening, replaced eventually)
I once added Trochus snails from reef cleaners direct to the display 4+ months ago.

Just give me your opinions.
 
Wrasses flash often and stick their noses to the glass while they follow their reflections. The blenny may have internal parasites so I'm not sure what you could do for that. What kind of blenny? Are you providing it with algae? Many species require that daily. Clowns often swim weird. I wouldn't treat for anything until you are sure of the problem.
