Dead CB and now ICH

[teog]

Hey everyone I brought home a small purple tang for my 90reef on Tuesday. I acclimated him over 1 hour. I also have in the tank a coral beauty,mandrin goby, seabae and maroon clown,six line wasse and flame hawk. All my fish are small in size.
On Friday my CB was died. All fish have been in the tank for 9-11months no problems. This evening I noticed small white spots all over the purple tang. Im aussuming its ICH even though Ive never had it prior. Can he break out an ICH in 4days? IS my CB related to this outbreak or stress for adding the tang?
Nitrate, amonia and Nitrite are undectable
Thanks

The new fish brought in the ich and now all your fish are contaminated.
Hopefully you have hospital tank and will be able to treat your fish, otherwise, there is no effective way to treat ich in a reef tank.
