restocking tank after treating ich?

[lunning]

I am almost through week one of treating my domino damsel, yellow tang, and two percula's in a qt. I was wondering if my tank will cycle again if I added the tang and clowns at the same time? The damsel is going back to the lfs after it has been treated. Should I add them a week or two apart, or just restock all at once?

you should wait at least 4 weeks for the parasite to die(without fish in the main tank) and also treating the fish for 3 or 4 weeks.............

I added a clown, six-line and a two spot goby to a 90 gal with no efects. All three fish are under 2 inches and that may have made the difference. I would suggest adding the clowns first and then waiting a week or so for the Tang as you only have a 30 gal. It will give the clowns a chance to settle in and your tank to restabilize although I don't think there will be much of a cycle.

You should let your main tank go fishless for at least 6 weeks prior to replacing the fish.

I know I was just curious for when the time comes.

i see.. I don't think there's a problem with adding all the fish at once.....
make sure you acclimate them and i'd do a 10% water change the day after...just my two cents
