I really dont know how they get out. I use something really similar to a criket keeper. But with out the tubes. I wasnt told how old she is. Appx Size is about 8-10 inches. Does ano one know how old that is, in comparision to length. Feeding super or silk worms would be ideal. considering that are escape artists. I cant find anything in my tank. its had a screen lid, with no spaces for them to get out, and i cant find any spaces in the little keeper.? Each cricket i i find is adding to my frustration. Im thrown a blank :|
