Help me ID these..

[amdninjaboy]

Just trying to figure out what hitchhikers Ive got here.. Ive got 4 things on this one piece of LR that Im trying to ID.. 2nd pic shows yellow blob, not sure at all what that is.. first pic shows all the rest, about middle of pic is larger anemone?? I think?? Then there appears to be a mushroom like thing just above that, Looks green in pic but its usually a maroon color.. Both of those seem to open and close up with the lights goin on and off.. Then there are many of the other fan tip things.. They are bright green and close up when the moonlights come on.. I was thinking aptasia but have read they are yellow or brown..
What does everyone think? Other pics are just of the fishies.. 'Spike' the porcupine puffer and a pair of occ clowns.. I also have a lawnmower blenny but he hasnt been photo friendly yet. Spending most of his time hiding in the rocks..

Thanks for any help,
Shane.

The yellow ones are yellow polyps and sting other corals and grow rapid. Once the inhabit a rock it will take it over. Some people like them.

Yellow blob looks to be a sponge of some type-looks like it has a couple of little tubes on the right side that it siphons water through(good thing).really looks like you got a real good piece of rock there with good growths on it.

First pic looks like a majano nem, which you don't want, surrounded by yellow polyps (which are a coral, easy to care for) the rest looks like GHA.

Hope you have a large tank for that puffer, they get big

Ya tank is a 90 Gal... So how do i get rid of the mejano??

aiptasia x will kill majanos over time. They're a little harder to kill so it takes a while.
