What are these corals?

I got these about a week ago and they have areaddy started multiplying.

And these i'm just curious about.

1 not sure
2 looks like a closed up sympodium with an apstasia beside it, sympodiums dont like to much of a salinity change. it might stay closed for a couple days, if it does not start to open you may lose it.

1. Yellow star polyps

The "yellow star polyps" are neon green. I have green star polyps that grow on a matt-like thing they create. These seem to spread just like aptasia. Does that still sound right?

Hey nice to see the corals are starting to spread. Like i said with mine they usually come and go but never caused any problems. Hows the others doing for you? BTW someone is coming to pick up the rest of my livestock/rock so I will be able to get you the whatchman very quickly once I get the rock out. I will even deliver him.

I had yellow star polyps that morphed into a dull yellow and spread like that. Unless they were never YSP?

I am about 99% sure that #1 is a type of majano anemone...

Scale is hard to determine, but photo one certainly looks like Mojano. Get ALL of them out ASAP, regardless as either way they are a pest.

Photo 2 , get the aiptasia out ASAP as well.

Definitely a Mojano - hurry - they will take over your tank- and peppermints, copper banded do NOT eat them.
