Unknown species in my tank.

This thing looks weird, it doesn't look like a common pest that people in RC talk about. It's very small, so it was very hard to photograph with my camera.

Is this bad? They reproduce moderately fast.

Looks like a sea spider to me. It could also be a brittle star, but it doesn't look like the stars I have in my tank.

Not really a problem and they are generally self limiting.

I had them. I siphoned them out when I could, but I didn't get all of them. In my tank they disappeared on their own.

Wow, looks like they just disappear by themselves.

Thanks everyone.
