white things

Any one have a clue on what this is? I have been looking at it for 2 days now, have not seen any tentacles or movement.

 

What thing, the one in the middle? Got a macro shot of it? I'll pull your photo and fix it up if PS to see if I can ID it.

 

This is the best I get from my old digital camera.

 

Looks liker som e sort of tunicate or sea squirt to me!

 

Is that a good thing for them to just start showing up 3 months after adding the LR?

 

It's all good, really cheap new stuff, eh?

 

Ah, its a vessal sponge. A good thing, a freebie.

 

Cool, I like the good freebies, thanks Craig_Manoukian and Gresham.

 

Ah, its a vessal sponge.
