I recently had an ich outbreak due to not quarantining a new Tomini Tang (I know, I'll do better from now on). I'm about to pull all the fish to quarantine for 8-10 weeks and treat with copper. Question that I can not find a straight answer on: should I pull my inverts and corals as well (hermits, snails, and a few Green Fluorescent Mushroom corals)? I keep finding conflicting information on that, but I'm not sure it's necessary.
Also, I've been wanting to add more corals and my tank parameters are good so would the fallow period be an okay time to start introducing a few corals to the tank since they are not hosts to ich?
Finally, how do I keep the cycle from breaking in the tank with no fish around to feed the BB in the LR
