What do you mean? I have kept both of those on more than one occasion.LOL thats great!My family might kill me if I try taking the whole house over for my pets again. (And by the way; I found that garter snakes just love Christmas Trees!) So my mantids will have to make do with a small 2 1/2 gal. fish tank. I only plan to keep one or at most three in there at a time, but I may have to start saving up the deli cups.
Rick you might wanna try a more aggressive and larger species such as Chinese or Giant Asian... Just an idea...
