Arrow Crab Having Babbies?

[Chrisz]

Ok, I though I knew how the birds and the bee's worked but my arrow crab keeps having babies and there is no father in the tank, no fish only corals.

What ever is coming out of the crab looks like little tad poles, some of them swimming some of them not moving, all of them gone by morning. This happens at least once a month, so what do I have going on here?

Looks like the zoeae larval stage of crabs
