Ok, i am very curious, but i am thinking there has to be an easy way to do the venelation. i had a dubia colony but a previous landlord came in one day and one went walking across the floor. (i had just returne home from work to find out my cat got into my walk in closet and the screen had been smashed in because she decided to climb on it. bad hubby's that don't know how to close a door :wink: However i am moving in the next month an want to start a new colony with 5 dragons, 4 leopards, 8 tarantulas, and various otherreptiles it is getting expensive to feed. can i attach a floor vent or circular vent with window screen glued into it to make the venelation more stable? I know alot of local people who are always downsizing their colonies and it woul be nice to be able to take some off their hands if possible. also, is it a good idea to rotate adults through tubs like i do with my mealworms (don't worry they are for the leopars and tarantulas only, not the beardies) I rotate my beatles for the mealworms every 2-3 weeks, though for the dubias i was thinking more a matter of every month or two or will that just stress them out more? I know "Jamies tarantulas" has a breeder kit but the way i look at it it would have near enough room to substain my feeders that i need.
