Home from vacation . . . Could use a little advice.

[Enigma]

Well, we're home. The tank survived, though it now has a nasty cyano outbreak.

What I thought was a parasite of some sort on my black occ.'s fin most certainly is a parasite. It is larger, and the clown is dive bombing my torch corals. It has is displaying no interest in the cleaner shrimp I added to deal with the parasite. I'm guessing that it is a fluke, but i am not 100% sure.

I figure the parasite must have come in on an invert (snail or urchin), as this tank was fallow while my fish did six weeks in the HT (two week Prazi-Pro and four week ParaGuard treatment).

I'm annoyed.

Anyhoo . . . I do not want to pull fish and leave the tank fallow again. I'm looking at either a Prazi-Pro treatment in the display, or that medicated food (long name which escapes me right at this moment, starts with an "M").

I'm pretty confident in the Prazi-Pro. The fish can all handle it. I am a bit worried about my tuxedo urchins and cleaner shrimp. I would say the fish are more important to me than the inverts, though I'd rather not kill anything.

I'm not opposed to a dip of some sort: if I can get her out relatively easily.

Suggestions?
