sorry for cruddy phone pic.. my lights just went out, so if we need better photo, I'll take one tomorrow..
but is this Aiptasia? it's brown with long tenticals. I only see one- just peeking out from under that frag plug.
I did get some frags from the Reef-a-Palooza few weeks ago, nothing else was added to the tank. I did dip the frags too prior to putting in the tank
This tank will be broken down in a few months, how can I ensure this won't get in my new tank?
