Most adult Candoia will readily accept rodents, but there are exceptions. C. b. australis and C. b. bibroni will eat rodents, but many favor birds (chicks and quail are favorites). C. carinata and C. paulsoni may be picky and only eat anoles or tree frogs (Hemidactylus frenatus and Hyla cinera are the easiest to obtain). I’d imagine C. superciliosa follows suit since they are so similar to C. carinata.
This is probably why they aren't popular in the hobby. That kind of specialty food for the picky eater is not cheap nor common.
