Baby critter ID

[Devin_R.]

Hello,
Can anyone ID this critter I found swimming in my tank earlier. I caught one to see if I could get a better view, but there were quite a bit.

It seems to have a little spike jutting off the top of its head, so I'd say crab larvae. What crabs do you have in your tank?
