How old is your guy? If hes around 6 months old maybe 2 times per day - I would be feeding salads w/ some worms in the salad like 1-3 supers maybe 1-2 horn worms - add a silk or two they are a good staple feeder as well - that will balance out his diet along w/ those BSFL in the salad too - then after a hr or so add your dubias to the salad take a little out but leave some in there so hes getting salad too - add like 5-8 roaches -- see how many he eats - he may not eat all of them from eating the other stuff- then offer some dubias in the afternoon -- you can dust the dubias or you can dust the silk worms - the BSFL dont need to be fed - just keep the dirt a little moist if it starts to dry out - I never had to feed them cuz they were usually all eaten up by the time the dirt was drying out- keep them on your kitchen counter-- offering a variety of insects and worms is good and greens/ salads - plus it will balance out his diet-
