My 5.5

What are the two polyps in the middle? It looks like 2 huge aiptasia to me, correct me if i'm wrong.

Those anemones came on the shell of a large hermit crab. Crab died, the little hermits always stole his food. I have no idea what kind of Anemone they are. There's a closer shot in my gallery.

tank has good potential...rock setup is nice...needs more life though.
