I am new to saltwater, and recently discovered my 6 striped wrasse has ich! I also have snails, hermit crabs, and an emrald crab. Now, I am going to quarantine my 6 striped wrasse into a different tank. But as I do know snails and crabs can not catch ich but can hold it, should I also remove my snails And crabs from my tank or let them stay in their as I let ich die? Also, can snails and crabs keep ich alive? Lastly, how long does ich take to die? And do I need to medicate the water of my display tank? I do know that my crabs and snails can die from Ich meds. I don’t know, what should I do i really need help as a beginnner.
