Need help identifying star

[dutt7]

Looked for a while and my best guess would be a spiny brittle star.

but this one is really large.

Any idea of what kind it is and whether or not it would be ok to put on a 12 gallon aquapod?

I was splitting some live rock to smaller pieces and he fell out.

also, any idea of what type of anemone that is?
think he will need to find another home.

I do not think its a spiney sea star and was unable to find a spiney brittle sea star, yours just looks like Ophiothrix sp a brittle sea star
