Are these corals?

[tdowning]

If so, any help identifying them would be greatly appreciated! Tank is 3 months old, both were on the rock. First one is a little bigger than a nickel, second one is a little smaller than a dime.

Thanks for any help!!!

Cup Coral?

Yes there teacup coral their tentacles will get longer, mine started off looking exactly like that I have two and they have gotten much bigger, it will get little white swirls on their legs. Pretty neat little things. Mine seem to like a bit of higher salinity.
