Deb do you at least see them carrying eggs?

I noticed that when I had shrimp and they carried eggs that you really needed to be there at the release because 5 minutes later they would literally be all gone. In fact, I didn't so much notice that suddenly there were baby shrimp but rather that suddenly everyone was eating like there was no tomorrow (shrimp included).

That said, I notice that sometimes they would carry eggs and sometimes not, and I don't know if there was a rhyme or reason for the cyclical pattern.

I did notice that if a shrimp was about to molt, that the other shrimp would be very agitated and excited. The shrimp would step out of the shell and then suddenly the others would just descend on the molter. At first I thought it was cannibalism then I wondered if that could just be the window of opportunity for mating. Maybe the opportunity for mating exists only shortly after a molt.

Yeah mine have carried eggs a few times too, just never hung out late to watch them release.

Here's a link for a hatchery that has raised cleaners too
