Pink, Clear, and White?

[vw65bus]

Sorry this is my first post im new here and to reefing, ive got a 72 bowfront which will be a reef tank very soon. I need to know if this is bad or good. Thanks for everyones help and hope to be here a long time,

These are attached to a rock that was pre existing in tank when i bought it. About a week ago it started growing. The pink part is attached to the rock, clear tubes move around and the white ball on the tips of the clear tubes. I have 4 small patches one of which is on a small black rock by itself while the rest is attached to big rock and one big patch about the size of a gold dollar. And a pic of my tank, I know im getting a reef light soon,

Looks like Phyllangia americana (hidden cup coral) to me.
Perfectly safe.Its a type of solitary cup coral.Their non-photosynthetic corals.
Congratulations on your first corals,and welcome to the reef.

Thanks for your answer and i done a search and come up with this Pseudocorynactis which says This Pseudocorynactis from Fiji is beautiful but not safe with fishes and adjacent invertebrates. It is a voracious eater that has powerful nematocysts in the ball-like tentacle tips. I hope your right cause this page Aquarium Invertebrates says its harmful, man i hope not,

Those are pretty common hitch hikers. The good (or bad, depending on how you look at it) is that they don't live long. They will usually disappear within a couple months.
