Possible Hermit Crab Spawn??

[Brando650]

Woke up to these things floating around. They seem to congregate towards the top of the water. Nothing in my tank at the moment besides a few hermits. Any input is greatly appreciated!

Thanks.

Looks to me more like mysid shrimp. Good guys could've come in on live rock or from seawater

Yes, it is possible. Hermit crab larvae look just like that.

That is what they look like! Just a few minutes ago I witnessed the act. I was staring at my tank and it was 10 or 20 minutes after lights out and out of the corner of my eye I see an eruption. It’s a tiny little hermit crab spewing thousands upon thousands of these little larvae into the water column. It happened 3 or 4 times before the crab finished and they are just everywhere in the tank. I catch some with a turkey baster and put into a specimen container for closer observation and they are jerking around going towards light with their little yolk sacks. This hobby just keeps amazing me! I’ve also got a spawning pair of molly miller blennies in another tank. Now to figure out how to raise the larvae and find very tiny shells! LOL
