The cute little red & black baby conch that hitch hiked on my live rock is an oyster driller. He has devoured all the little rock clams & oysers I had in my reeftank. I am now keeping him in my 5 gallon with thumper my little green mantis shrimp. Any thoughts on what I should do with him? Anybody want him? Could he also be why all my snails & blue leg crabs disappeared?
