I purchase a lot of stuff from LLLReptiles and think very highly of them!!! That said there are many good feeder insects for your chem. look at the info on this forum and u will find all the good feeders you will ever need. A few examples are crickets that have been well gut loaded,roaches,silkworms,super worms in moderation,Phoenix worms and the list goes on. There are suppliers that will send u a mix of many different feeders in small numbers to give your chem a variety that will help insure good health!!! Feel free to pm me and I will give u some sources!!!
