They do look like your zoas lee, but they don't close like zoas (I have a couple colonies as well). I have 3 different types of these anenome looking things, all look slightly different. One type has bright green tips, there's about 5 heads and they do close like zoas, not as nice looking. They are in an ackward spot so hard to get a pic of. I'm just keeping an eye on them at the moment and see if they spread.

Yes, that is a chalice in the one pic - my blenny picked at it constantly, hence the white tips.

I'll watch the tank and see if the snail comes back out and try to grab it for a better picture. I'll also try to cut one of the nem things off and see what it does as well. Thanks for all the input. :biggrin:
