ich showing up in old livestock?

So something is amiss with my royal gramma. It has tons of tiny whit especs on it's fins and around it's head, certainly looks like ich to me, and it keeps flicking against the rocks.

I had 3 other fish... but all of these fish I've had for well over 6 months, the Gramma has been in my tank for probably a year and a half now.

I started a completely new saltwater tank. Dry sand, marco base rock, cycled with seachem stability and MB7, no live rock from old tank at all. No new corals at all, they came from old tank. The only thing that came over from my old tank, which the fish never had any signs of disease whatsoever, was a single frag plug the toadstool leather is on. Everything else was put on new plugs even or simply removed at the base and transferred over.

Was a used tank that I picked up. This tank sat with a 5:1 vinegar solution for about a week, thoroughly cleaned, then dried out and filled up with fresh ro/di water and instant ocean reef crystals.

My one black/white clownfish is doing great. Not a sign of problems, eats like a pig, swims around happily. I did lose my other clownfish during a nitrite spike when I moved everything over. This was about 2 weeks ago I lost it, no spots on it or anything, could tell the nitrites definitely affected it as it became very lethargic, yet wasn't breathing very fast like it had burnt gills from ammonia. I had been using prime to detoxify the nitrites during the spike, but I'm fairly certain that is what took my one clown away.

Also have a scooter blenny, it's doing great and I'm adding some pods once a week to the refugium to seed it and get some spilling out to the display. It does eat pellets also that reach the bottom, so it's not starving.

Sorry for the long winded post, I just really wanted to get all the information up there. My QT isn't running right now as some of the stuff needed a thorough cleaning since it was my old display's sump so I tore it down with the thoughts of, hey I'm not buying anymore fish for at least a month or two to let this tank establish, I should be fine. Unfortunately for me, with my work schedule, I can't really do much till this weekend either :sad2:

I guess I'm just kinda lost as to how my gramma could suddenly get ich. From what I've seen, it's a parasite with a very definitive life cycle, way shorter then 6 months. This new tank also cycled without fish in it for a month and a half before I switched everything over. Any ideas on stuff to look for?
 
Ich can live on the fish without them showing any signs until the fish get stressed. I am guessing at least one of the fish must have had ich all along. If you don't introduce a new strain of ich in 11 months then they are gone, or 8 weeks without any fish to host on they will die.
 
Agree with the stress creating the opening for the ich. I once saw a tank get ich that had had no fish additions for six years- nor signs of ich prior. The tanks fish were QT before going into the system, and they had a UV sterilizer as well. There was repairs being done on the house the tank was in- and the front door was off for a day in january. Tank got cold- fish stressed- massive ich. I see in a balanced tank- ich is like mosquitos- a irritation- but not a death sentence- until the fish get stressed.
 
So is it a guarantee that 8 weeks no fish completely kills it or what? I'm kind of at a crossroads with my qt setup for another week or so.. and it still isn't cycled or anything. It's also only a 10 gal which would be bare bottom.. and no food for my blend.
Should I just try to treat the grammar since the tank is stable no or risk all 3 fish in a small qt for 8 weeks

Nothing is guaranteed.:) 8 weeks of no fish in the display may be enough to rid the display of ich, but 10-12 weeks is better and more likely to achieve this result. There is no point to treating any of your fish for ich unless you are going to treat them all b/c the untreated fish will simply re-infect the treated fish. As such, if you are not going to treat all fish, then you are better off maintaining the best water quality and nutrition you can and hope the fish can fight off the parasite and reduce the infestation to a small enough degree that the fish are largely asymptomatic.
