What else is growing on this frag besides the zoas? I can see a feather duster on the side but i'm not sure what the purple flower like stuff is ( not the coralline). I'm thinking of buying this but I want to avoid surprises.
second question, When buying turbo snails or any snail for that matter how can I avoid introducing any unwanted algae or parasites into the tank? I know I can quarantine them but are there other ways?
