the second picture looks like a glass anemone , i have a big one of those. i feed it often, even though im told its bad and should kill it. it hasn't spread in the 2 years its been there. i like it.
The first is either a tunicate or sponge. The second is a cup coral, possibly Phyllangia americana. Is your rock from the Caribbean? IF so, this is a nice hitchhiker. Feed it regularly with cyclopeeze and other small food particles and it should do well. Here's a link to another picture of one:
I am pretty sure this rock came from the Caribbean. It has a lot of helimeda and other macroalgae, and it has pretty low density (not very heavy when picked up). I got it from a LFS, and didn't think to ask. :roll:
The one is a cup coral, like stated. Which also points towards the origin being Carribean. I am not sure about the other one yet. I will keep an eye on it....
