What’s that there?

Just spotted this this morning when lights were off and my mushroom was closed up. The thing sticking up. It’s kinda like a pineapple sponge but looks clearer.

Sponge or tunicate. Harmless

Kind of looks like a tunicate. Can you see if it has 2 openings?

Streetlamp · Feb 11, 2020

Its normally hidden by the shroom. I'll try see again tomorrow morning. Are the two openings at the top?

I couldn't see the two holes due to positioning.

This is my red tunicate, it has a smaller opening along the other side, if it has a single opening it is a sponge.

That’s beautiful!!! Oddly i have sponges with more than one opening but agree, it must have 2 to be a tunicate.

Thanks, my blue sponge has about 12 openings but each is it's own thing / system.

I imagine you bought it? I really like those. Oddly I saw tunicates on frag plugs at my LFS once. Never ever seen that in my life.

My reefing buddy snapped the pic.

Yes, it was in a UK tank for about 7 years before I got it, I've had it for about 3 years.

Those are very nice.

Definitely are. But I’m not sure how long they’ll live out of the ocean. I had tunicates hitchhike before and lasted roughly 3 months before one day completely disappearing.
