Hi all! Thanks in advance for any help! I recently bought a mushroom from a pet store in Salem, NH. The mushroom came on a very small rock that only cost 9.99! I was excited to find a coral so cheap at a store. On the back of the rock a small orange thing started to form. At first I thought it was a sponge or something. It has grown quite a bit in less than a week, but is still very small. I returned to the store and asked about it because they had several other rocks with these little yellow corals on them. He told me it kind of looked like a tree, was a soft coral and non-photosynthetic. Does any one know what it is?

Any Ideas?

Also, while asking for help, has anyone seen this type of mushroom before? it came as a hitchhiker:

Thank you!

Blue spotted mushroom(no real fancy name).lol
The small softy growing appears to be a nepthia.
Some of the other yellow stuff could be simply sponges.
