Strategy For Treating Ich After Infestation

[JohnV8r]

I have a 194g system/175g display reef tank. I recently discovered ich on a powder blue tang. The cysts cleared up quickly and the fishes overall health is good (good appetite, good activity, etc).

Since I have a reef with SPS & LPS, treating in the tank is out. My questions are as follows:

1. I have not had a fish die in more than two years. Water quality is excellent. Am I better off acknowledging there is ich in the tank, hoping the fishes' resistance against ich is good, and leaving everything alone until there is a reason to take the tank down or should I pull the fish out, try to wait out the ich life cycle with no host, and put the fish in a hypo salinity quarantine/med tank?

2. How do I introduce fish into a hypo salinity tank?

3. If I have 12 fish, can I QT them in one 26g tank, or should I separate them into two 30g tubs?

My vast preference would be to hold off until there was a reason to pull the fish out. However, if having ich means I should take drastic steps with an otherwise seemingly healthy group of fish, I will.

Thanks in advance.

Found the answer to Question #2. Please disregard.

This is coming from my own experience with ich in my newest tank. I brought home a blue tang and added it to the tank, when i got it at the store it had no signs of ich. The next day, it had a few white spots on it. I immediately treated the tank with stress coat so as to prevent it from spreading. I fed the tang and he ate so i just let it ride out. After a few days the ich disappeared and hes been fine ever since.

As long as you dont see any other signs of the ich then youll most likely be fine. The ich usually comes out in fish under stress. Being introduced into a new aquarium could be enough to bring it out. Just keep an eye on them.
