Any idea what this is?

I have couple of these growing on a rock in the back of my tank. Any idea what it is?

Either sponge or tunicate I would say. Sure is a pretty growth forum.

Thx Tahoe61! Maybe a type of tunicate. I don't think it's a sponge only because it grows from a 'stem' attached to the rock. I have to try to get a better pic. I took this with my phone because it is 100x easier to uplaod a photo from there. So it is not the best quality picture.

Here is a pic that you kind of see the 'stem'

+1 on tunicate. It's gorgeous.

Thx Lionfish! I have had this rock for 7 years and never noticed it before! That's one of the best benefits of live rock! It just keeps giving and giving

Yep!!! I agree. Enjoy it while it lasts.

Are tunicates hardy? Can they be cared for and propagated?

 

[The-Russ]

Most do not like a lot of light so they don't grow well in reef tanks. I have heard that Some people have/grow them in their sump

Yeah. Was reading about their nutritional requirements as well. Perhaps it would require a dedicated tank. Beautiful variety though!
