Okay guys, I need y’all’s help. I bought a purple tang and a lawnmower blenny together from the same store, and dropped them in a tank. The tank had a clown that the purple tang beat up really bad so I moved him. Five days later the lawnmower blenny is dead and the purple tang died last night, both from (presumably) a severe case of ick. White spots, clouded eyes, looked exactly like ick. So now I have a tank with zero livestock but a recent record of ick, how long should I wait before trying to put fish in there? Is there some medicine I can dose the tank with that won’t harm my corals? Thanks!

And no, you can't put anything in the tank with Coral that will reduce the time it must stay fallow.

I will say though, that depending on your risk tolerance, in most cases 45 days is long enough:

In most cases, 45 days worth of isolation will eliminate most threats. This includes velvet, brook, flukes, bacterial infections and all but one strain of ich. In a 1997 study (Colorni and Burgess) it took 72 days for all the theronts to be released from a group of tomonts. However, that study has been the subject of debate, because the longer excystment period occurred at 20C (68F), and it is possible that lower temperature slowed down the parasite's life cycle. More on this can be found here: Marine Ich and Temperature

Personally I waited 76 days to be on the safe side before I moved stuff exposed to Ich.

Thank you so much! I was kind of thinking that the fish were weak to begin with because originally I put them in with a clownfish that I've had in that system since the beginning and he doesn't have ich and seems just as healthy as ever. I'll keep livestock out of the tank for at least the 45 days.
