I qt all corals and inverts in a fishless tank that has been up over 2 years. I have a gem and yellow tang that are done qt. The last coral came out of frag tank January 1st. They were in there for 45 days. Would it be safe to add the tangs for observation. I would think there would be no ich cyst. Would like your all opinions? Thanks.
