Is this normal?

[kaseysfan22]

Hello. I bought two juvenile Chinese Water Dragons about two weeks ago. One is roughly three inches snout to vent the other is only about two inches. The bigger one is nicely rounded and has a pretty green color, however after about five days; the end of his tail fell off. I'm not sure what happened I haven't even been handling them. I pet them occasionally, but I wanted them to get used to their new home and not be too stressed. However I don't think that’s normal. The smaller dragon in a dark olive/brownish color and he seems kind of skinny. Why isn't he green too? They get along well. I have never seen them show any aggressive signs towards each other and more often then not they can be found together. They love to sleep on each other. They both seem to be eating well, but both seem kind of lethargic. They jump around sometimes, but most of their time is spent sleeping. And neither one goes into their pond. Should I be worried?

The hot end is 85 with a basking spot of 92. The cooler end is 78. They do have a uvb bulb, but its a compact not a standard tube. Does that make a difference? I got them at petsmart, which was not my first choice, but they were the only place I could find that had captive breed babys. I'm reposting to lizards now. Sorry and thanks
