For one reason or another my turtles have both died. They were young red cheeked sliders and died very suddenly this morning. I morn their passing but I have a lot of money invested in their enclosure. It's a 30gallon aquarium, pump, two heating lights, turtle dock, and cherry wood stand. I'm still wanting to make use of it but I've gotten more into insects lately and am planning on using the same setup, minus the pump, for some display insects.
I have around 10,000-12,000 Blatta Lateralis I was using to feed my turtles, started with 100 from James at Blaberus.com in August then added another 1,000 from a kind gentleman on the boards Jay Host298.com, and I don't want to just kill them off (also have a good $100 invested in their setup). So I'm wanting, if this is possible, a communal insect species that I can breed, I've found I really enjoy doing it, that is carnivorous and preferably non-venomous I can use for the setup I already have with additional purchases being kept to a minimum. My current preference is a scorpion or mantid species but I can't find any that are non-venomous, for the former, or communal, for the later. What advice do you folks have for me?
Edit: lol The thread title obviously should be "My Turtles Died
