It's a brittle star . Totally harmless.

brittle star, good scavenger... unless its green.

Looks like a brittle star, good cleaners and safe.

The mini brittle stars are good to have. The green brittle stars (much larger than that one) can eat fish and inverts.

this one has green, how do i know if it is a baby green one? it has green and maybe brown ish stripes or dark green and light green

put it in your tank its a good one

it is in there.

thanks

Poor little fella is missing a couple of arms. Looks like he's growing at least one back.
