So my friend and his little brother both got baby bearded dragons for Christmas. I think that they were maybe three or four weeks old. They were both the same size when bought. Now one is dramatically larger than the other. It seems that my friend's dragon is only slightly longer and larger, but his brother's dragon is much larger. The dragons are very different in looks. The small one is yellow in color and you can tell that he will be very spiky when he gets bigger. The larger one is dark brown in color and much smoother.

Both dragons live in the same conditions (though in different tanks naturally). Both hot spots are around 105, cool spots around 85. They are fed the same diet: consisting of mostly small crickets and some collard greens, both sprinkled with calcium a few times a week.

There are a few behavioral differences. The large one is fast and moves around his cage a lot during the day and never fails to catch the crickets. It also doesn't hesitate to eat a variety of greens and veggies.

The small one hardly moves around except when crickets are in the cage, and even then it seems he is not as energetic when chasing after crickets. He often misses the cricket he's going after. I think this may have something to do with his eyes, it seems like he has a harder time seeing the crickets. We noticed something was wrong about a month and a half ago because he spent most of the time with his eyes closed. We replaced his UVB with a different one because I read several reviews that said it was damaging to the eyes of lizards. When he continued to keep his eyes closed we took him to the reptile vet who suggested gently swabbing his eyes daily with a damp q-tip. She thought that he had a bacterial infection in his eyes. So we did this and it definitely seemed to help. He stopped closing his eyes for long periods. But that didn't solve the problem of his inactivity. He also doesn't seem to like eating greens as much as the other dragon. He will only eat kale, whereas the other one eats carrots, apples, and other veggies.

Is there anything we should be doing for him?
