As previously mentioned, it's partly genetics and partly diet but by no means an imminent problem. Most importantly of all, is a balanced and varied diet. Personally I would steer clear of feeder fish, especially goldfish, obviously. Cut strips/chunks off a cheap and lean fish like Tilapia. Things like crickets and Mealworms are fine but in moderation or even as twice weekly treats perhaps. I'm lucky enough to have a steady supply of clean bred Blaptica Dubia roaches which are very high protein and low fat. I was never able to persuade my MGXB to eat pellets but went a stage further than gut loading Super Worms. I simply chop the head off, scrape out the insides and replace them with three Hikari sticks per worm. My fella loves them!! I occasionally put a slice of raw garlic in as well. This is great for appetite, interior bacterial infections and general health. Balanced/varied/imaginative diet is king! Good luck!
