Is this a Mushroom?

[Aquatic Jewels]

Ok guys, my LFS Owner told me that this was a mushroom of some sort and he wanted me to raise it and hopefully produce more for him. I don't know if it is a mushroom or some sort of anemone as when I hold my finger on the tentacles, it almost feels like it is shocking me (like a lite battery shock). It is soft and starting to stretch out. When we spot feed it, it takes it pretty quickly and wraps completely into itself.

I have a hairy mushroom that's similar to that (just green).

What kind of mushroom is it though? Would it be a type of rhodactis?

 

[i cant think]

Yes, hairy mushrooms are of the genus Rhodactis. This looks to be a young St Thomas Hairy (Rhodactis) Mushroom.
