I've had a bubble tip brittle star for over 2 years now and he's just too big for my tank. He's about 18" in diameter now and he can reach from the front to the back of my tank. We were going to transfer him to my hubby's 180 once we get it set up, but he's keeping me from getting the clean up crew I need in order to keep my tank clean. He'd be fine in a larger space, but the bottom of my tank is only 18"x20" and with a star that large, it keeps eating my snails. Anyway...he's up for grabs if anyone wants him. I'm not comfortable shipping him (I feel like he's one of my kids) so you need to come get him. I'm in south AL...pm me if you're interested.
Here's some pictures...
