Great work! What was your trick? I've had three that chow down anoles and house geckos but have no interest in anything else. Fortunately for me it's quite inexpensive in New Orleans (even today in the balmy 65 degree weather I could find lizards outdoors). I'm kind of fond of the native herpetofauna though and would love to switch them over ASAP.
