@Ry Zen He'll get fat just like any T in his species, female or male. Males only get the long-legs small-abdomen thing going on after they mature, and even then some mature males can get pretty fat if they still have an appetite.
@Ry Zen I have all of my Ts on a weekly to bi-weekly feeding schedule, depending on their size. Most of my Ts get crickets or mealworms, but if they're large enough I'll offer superworms, or even hornworms once in a blue moon. Dubia and several other roaches are also popular feeders.
Here's my juvenile male B. cabocla looking very nice after a molt.
