It Was Free BUT What Is It ?!?!? lol

[FattyK21]

i bought a few new corals and this il guy was attached to one of the frags so i got him for free but i really dont know what he is
I did glue him to a lil piece of rock so he at least had a base but any ideas ?

looks like a little zoanthid or a paly

I agree it looks like a paly or zoa. I got one that looked very similar a while back and once it settled in turned bright green and spread like wildfire. Became a nuissance and covered up my good zoas quickly. Needless to say i got rid of them

yes those can really take over
