I've used 2 different methods for veileds. First i chop up in a food processor bite size pieces and put in a small dish. And i've also hung pieces with a clothes pin out of the basking area. Each cham is different as to which way they will prefer but if he hasn't had them from the breeder don't be surprised if it takes him awhile to catch on. Just replace the old with the new and he'll catch on eventually. Considering his size make sure you take out the veins if your cutting it up.
