Getting mini brittle star out of rock?

[Elo500]

I pulled a rock out and placed in bucket to treat aphista issue but I can see several brittlestar legs sticking out of the rock. How can I coax them out of the rock so I can put them back in the tank ?

Try putting something edible on the bottom of the bucket, they might smell it and crawl out. They hide a lot, though, so they might stay put.
Be sure to stick an airstone in the bucket so nothing on the rock smothers.

I've done it with both taking the rock out of the water and waiting for them to crawl out or you can do a fresh water dip and they will come out.
