there was a guy on here that has a ton of them and he said qt was stressful for them and does not do it but he also feeds some form of medication in all of his fish food directly to his reef tank saying it had no effect on any of his corals
It must've been prazi, metro, or GC, which like @mfinn said, doesn't treat for the nasties and I just can't take that chance in my dt. I don't want to go through that again ever.There is no medicated food that will kill ick or velvet.
