I have a neglected 37gal tank, but that is about to change. I have 1 pajama fish that has been the only fish for a year. I want to turn this tank into a reef with just the 1 fish and add hermits crabs, snails, button polyps, mushrooms, very easy stuff to maintain. This is my daughter's tank and I can not under any circumstance allow her fish to get ick. I've had a easy corals, inverts, no fish ( sorry, I forgot the acronyms)in a different tank before. I think I've forgotten a lot. Do I need to quarantine all inverts and corals that I want to add? If I do quarantine, should I buy corals and inverts at the same time and quarantine them together, or buy them separate?
Thanks for any info, I feel so ignorant
