Hey Spyker, good chioce !! you can not go wrong with roaches. but also bear in mind, that variety is always your best policy ! i use roaches, meal worms, super worms and crickets.
I have started a Phoetalia pallida (Pallid Roach) colony, which is awesome, but they climb... which can amount to a few headaches and escapees.
then im getting in a whole bunch a Blaptica Dubia (Orange spotted roach). which dont climb nor fly. but cant give you much info on these guys, since i havent had any of them.. but 1 thing i can say is.... most people on other forums swear by them...
