How does aptasia get introduced into an aquarium? I just found one in my fug. I've had it set up for 3 weeks now and just like that it appears in there. How can that be?:notsure:
It hitchhikes in on live rock. I just put a couple small pieces of rock in my fuge and about a week later I noticed one. I blasted it with some boiling water from a turkey baster. I hope to keep it under control before it starts spreading.
