critter ID please. Isopod?

[skene]

Found these while dipping new corals in Bayer's - Sizes varied but biggest one was about 1/8" All of them died off quickly in the dip. They seem to "roll" up when stressed.

Are they isopods? Hard shelled body with a single "stinger" in the rear.

Wanted to determine if they are live-bearers or laid eggs.

Looks like isopods to me. I am guessing Sphaeromatidae. I don't think the are a problem.

Perfect, article says Sphaeromatidae are harmless scavengers. Thank you Doc and cloak for your help.

. Can anyone identify this? I think it's eating my copeopods ?

You should have started your own thread. It's a harmless flatworm that eats copepods.
