Sooo I made a stupid decision with the new 90g. It had 2 clowns which came out of my other tank. Decided I wanted a blue eyed tang at the LFS 2 weeks ago, they held it. Looked like it was in great condition. I had planned to qt but my qt is only a 10g so I ended up putting the fish in the 90 thinking that it would be more stress in the 10g and I had not seen any disease so hoped for the best knowing it was the wrong thing to do. About 2 hours after the fish went in I noticed a couple spots. After a total of about 5 hours i pulled the fish out and put into qt. Do you think it was too late in terms of infesting the 90 with ich? More concerned about passing the ich on to the clowns at the moment.
