yes. as long as there is enough space to get out of sight and claim territories. ur gonna have to make about 2 seperate basking areas for them to split and dont get more that one male.
Fruit flies and pinhead crickets would be great for baby and young pygmy chameleons but once mine get older these items are far to small for them. I feed my pygmys 1/4 inch crickets, tiny silkworms and the occasional moth and even more occasional wax worm.
