Mushroom coral??

[Munch]

This little fella was in the tank when I got it and I was told it was a plate coral but that was all the info I got. It was sitting on a rock but kept getting knocked off so now it's just been sitting on the bottom of the tank but seems happy. Sometimes it blows up like a jelly fish or else it's pretty flat with little fingers coming off it and it's about the size of a nickle.

Wondering what it's official name is, how big could it get and if it's OK sitting on the bottom or should I be doing something else with it?

Thanks!

It's a short tentacle plate coral. It should be placed on the sand bed. :)

It's an ADORABLE short tentacle plate coral. LOOK HOW TINY IT IS!

Thanks for the replies, very helpful.

And yes, it is very tiny but it sure is animated and interesting to watch.

Yup it is a plate coral.
It is one of the few coral species that actually do not attach to a substrate and gets knocked around in the reef.
The sand bed/bottom would the the safest spot for it.

I love plate corals but I cannot keep them in my tank because my crazy clown tries to host them and ends up injuring the coral :(
