Brittle Star Hitchhiker

[Axiomatic]

I just got a new frag of zoas and I noticed a small dark brown brittle star with striped legs was hitchhiking on the frag. The body is about the of a pea. I have a 46gal hex.

I know some brittles are bad news (cant remember which ones), is this one okay to drop in the tank to help the cleanup crew? Also, how big do they get?

I am trying to post a photo to help with the ID.

Thanks,

That one's a fine upstanding member of society and you should be pleased to have it in your tank. Size varies - without being able to identify it we can't say for sure. Probably will stay small.

Thanks for the info!!! Hopefully he will not get too big
