ARGH! Mantis shrimp have bred!

Yes, it's true. I have been fiddling with this x-terminator mantis trap, and
although I succeeded in catching my gorilla crab, I have at least 2 mantis
still in my 40 gallon and now they have bred. I noticed an unusual amount of
clicking the night before, so much so that I was convinced they were
building an underground parking lot in my tank. Anyway, I wake up this
morning and I see a 2" mantis sticking its head out of its hole. Then it
extends its arms and releases 10-15 little mantis shrimp into the water.
This action continues every 20-30 seconds. I have literally hundreds of
mantis shrimp fry swimming around in the tank and refugium. This is exactly
the opposite of what I was hoping for when I got into the hobby. Is here
anything I can do? Is there any demand for mantis babies?
