velvet has totally wiped out a tank I was in the process of tearing down all the fish dies except for 3 clowns a sixline wrasse 2 big eye squirrel amda large foxface. My dilemma is that there are a few rocks with coral still growing on them that I would like to save for my new build also there is a black widdow nem algae is taking over and I think that it will strangle whats left of the coral fragging the coral isnt really a option as they are attached to large rocks what should I do?
