Yes, I'm taking about the orange/red thing under the damsel's belly. I was thinking it was some sort of sponge. Are they fine?


As for the aiptasia... I know those exist. They are all over my live rock from the only LFS here. Problem with those is I tried Joe-Juice, it got rid of of the ones I treated, but tons more popped up soon after. And unfortunately, I can't trust peppermint shrimp in my tank with my dottyback and damsel. So I'm at a complete loss with those.
