Hey there! Sounds like a healthy eater regardless of the fruit thing. If your dragon is only 3 or 4 months old, greens and fruits shouldn’t be too much of a concern right now. You want to be feeding your dragon about 80% protein from crickets, dubia roaches and occasional wax worms all dusted in calcium. Keep the worms to a minimum however as they are high in fat content and you want your beardie to get his protein! Like I said earlier, at this stage it’s all about live feed, greens should make up the other 20% of his diet. (Kale, mustard greens, squash) if you really want him to try fruit, try apples! (Sliced thin and small with NO skin!!) my beardie wouldn’t eat fruits or veggies until I introduced him to apples inside of his greens and now he loves it. Try orange or red fruits as they are visually appealing to your dragon. If all else fails, if he’s a big big eater then another thing you can try (and has worked for me as well) is putting your live feed inside of his fruit or veggie bowl. This will give him a better chance at *accidentally* snagging a piece of fruit or two. Hope this helps!!
