They sound like they would work with some of my frogs. My P. sauvagei search every corner of their tank, even after I feed form a camoflauged bowl. My african bullfrog sees everything, and so do my big-eyes (L. flavmaculatus). Where do I get lobster roaches or hissers? We have hissers at the zoo and they can climb glass, can the lobsters? Not sure how my mom will feel about this...
