Thanks for that. I was planning to put them into a 30g observation tank. I could def treat them with prazi. and if needed I also have a 20gal tank I can use for QTI also have quarantined fish on order with Dr Reef. I have seen many many posts lately discussing flukes and ich after receiving their fish. Word of caution, you might place them in a qt tank and at least treat with prazipro if nothing else.
