Hi Jack
My two little fuelleborni's are F1 generation and the 'large' female is a long term captive. I don't find them hard to take care of. My temps are in the 55-65 F range and I do have UVB for them. Eating gut loaded crickets and I only handle them the one time a month for the weigh in. I don't know what the difficulty is in raising them, unless it's people who keep them at too high of temp and don't mist enough. I mist my guys twice a day.
