I have some white flower looking type of things growing on my live rock. Any ideas of what these things are? Also, are they bad for a fish only tank?

looks like colony of some sort of anemone. Any better close up Pics?

Magnified pic so can count the tentacles, that is if possible. This is one way to narrow down. Reef 101.

Does this help at all?

Thanx for trying but unable. I am very curious myself as they dont ring a bell.
Do they retract into tube or do they curl up and just contract llike an anemone when disturbed?

reefdude

my first thought was some kind of xenia... not so sure after seeing the tentacles.

cerianthus

Xenia? Really!
Try sending photos to Sprung, Knop, Moe, or editor of fish mag, etc, etc

reefdude

yeah xenia. I had some hitchhiking that looked like a daisy on my LR. LFS said it was more than likely some sort of xenia. It doesn't have those tentacles though!!!

cerianthus

Google for Epizoanthus arenaceus, E. paxii but doubt it. Try Alicia mirabillis, Pachycerianthus soletariusi , Maybe. Worth checking since you can make better comparison. who knows, it may even be juvie Jelly before becoming medusae.
