I have a beardie that is about 13 months, but he got tired of crickets so I switched to dubias. However, I am looking for another feeder to give him to change it up, I am wondering if silkworms would be a good one. (Background) He also gets a big salad daily and lives in a large 6ft tank. He is abt 18 in from nose to tip of tail, (tail is 10 in) any help is appreciated?
