Hitchhiker identity help

[Reef_rookies]

I have searched the Internet everywhere and cannot find what these 2 hitchhikers that came on my live rock are....please help! The L.R apparently came from Fiji. ..

Hard to see the second one (could be sponge or stony coral) the first pic looks to be tunicates.

I agree on the first - tunicates. Second looks like a sponge to me, but it's hard to see.

Thank you! I actually went to the local big Al's after posting and they also said the one pic was turnicates and the other one a sponge so you were right! Tonight we added a cleaner shrimp 2 ninja star snails..2 scarlet hermetic crabs and 2 zebra torches snails for our clean up crew! Finally the tank isn't looking so bare!

Here is another hitchhiker we have in the tank that I need help identifying if anyone could please help...I'm hoping it's not Aiptasial!!!

And one more that looks very similar...not the indicate...the other object that looks like a polyp with a white ring?

Yes. Aptasia.

Yes. Aptasia.

How can I be sure? I have been looking at other things on the internet that look very similar. Does aiptasia hide from light? Two of these things hide from it...one is under a rock away from light and extends more at night as I have been watching it at night with a flash light. The other one hides in a hole during day when light is on and also comes out at night!
