I am considering getting a bearded dragon as my next herp but I don't want to have to deal with all the crickets the babys eat im just not a cricket person. Anyway I was wondering at what age can beardies eat superworms as a staple insect? I will probably get a subadult beardie. And can I keep him in a 20L or should I go ahead and build his permanent cage? It will be 4x2 cage.
