Great write up Nick!
I use MantisPlace.com for all my flies aswell. I order 500 at a time along with thier food and containers. They are a great feeder and create quite a bit of excitement for the chams.

I usually hatch about 30-35 per deli cup and then refrigerate the cup for 30-45 secs before releasing them in the enclosure(slows them down). They re-animate shortly after I get the door closed and then the frenzy begins!!
I did however make a mistake when I first got them, hatching well over 100 in a cup and it turned into a mess. I tried to release 1/4 of them in the cage by removing the lid partly, but things quickly got out of hand and I had to close the cage door in a hurry and they were all released into a 18"x18"x36" enclosure, with a 5 month old cham.


She ate well over 50 BB flies!!

I had to take the cage outside to release the remaining, what a crazy mess!
