I got some amazing LR at LFS for 3.75$/lb and its filed with live stuff and vibrant colors. But I have found 2 things on them and one of them is "breathing". The shell looking thing is moving up and down on occasions.



and this one has little suction cups



Tnx

Nice looking rock!!!!
Dont think you need to worry about the 2 in the pic's for now! We can ID them later.
Looking at the pic's, in the back ground, top right of the first photo, I see what looks to be a Aiptasia. In the 2nd photo, top and a little to the left of the center, there is another.
Aiptasia will over run the tank if left, and will sting and kill fish and corals.
I would look at getting 2-3 Peppermint shrimp as soon as you can, They will eat Aiptasia like a kid eating candy, and IMO are the best way to rid the tank of the dreaded Aiptasia.

Thank you, I will have to go to the store this weekend.

I got the shrimp today but for past 3 hours they have been hiding in a little cave under the live rock. They are also rocking their bodies back and forth. Normal behavior ?

Hiding is usual for about every fish and invert introduced into a tank for the first few days. Don't know about the rocking. I think I have heard that they do that though.

Rocking or swaying side to side is absolutely normal.

The suction cups one are some kind of polyps or mushroom type. Not sure which one tho.

My "Pep Boys" Never come out except for at feeding time..And yes, the rocking is their little signature dance It's so cute!

Thanks for all answers guys. My tank is looking so beautiful right now, I am amazed! It was all worth close to 1000$ that I have spent already.

$1000 Is just the start. You know that MTS is not restricted to fresh water

Any chance of a full tank pic?
