I am getting set to remove all fish from my 125 and let it set for 30-45 days( Ick). Can I leave the serpents and Linckia in the tank? I am not treating it with anything. I have gone through several a couple of snake oils(Chem Marin for one) with dismal results( several deaths). 3 clams, 2 feather dusters and a few corals will be left too.
