something new in tank

[scrmom]

The items that need to be identified are on the piece of rubble. One is on the right side of rubble and the other on the left of rubble. I have two pics hopefully you'll be able to identify with one of the pics.

I assume you are talking about the pink things?
They look like tunicates to me. The pics are not to clear on my monitors. There should be two openings. One to pull in water, one to blow out. If there are more than two openings, then I'd say they are sponges. Either way they would both be harmless filter feeders. HTH

There are two openings. Do you recommend a book that I could purchase that would have pics of all the different things that could be found on rocks?

I don't know of a book that has hitchhikers listed. There is a thread at the top of this forum that takes you to a link that is helpful. And I'm more than happy to help where I can. WetWebMedia.com is a great resource if you have an idea of what you are looking for. HTH
