live rock hitchhiker identification?

[cipolla6]

Found some interesting live rock at the dreaded petco and decided to grab it. When I got it under the light a lot of things opened up. I'm new to salt but it appears to me that at least one of them are zoanthids but if anyone Conan confirm this assessment and I'd any of the others I'd appreciate it. I just want to provide optimal care.

The first pic looks like aptasia anemones to me. The others are zoas or palys.

First pic possibly aptasia it's usually brown tho it could also be some type of polyp the rest are all zoas.

first pics are absolutely NOT aptasia. they are what's called "yellow polyps" believe it or not. they're very similar to the polyps in the other pics, but they're a little on the aggressive side.

It's a close call, hard to tell from pic...Aiptasia do range in color, depending on lighting mostly. I would poke it, gently of course, see if it retracts downward. If so it's Aiptasia(opposed to just closing)

None of these are parasites, you have a few different species of zooanthid polyps here. That first pic is not an aiptasia anemone it is a yellow polyp.
