We just got a 55 gal. aquarium. The dragon is about 6 months old probably and is about 12-14 inches from nose to tail. My questions are about substrate. We've been using plain paper towel for the bottom of the small tank, but now that we've gotten a bigger one and he/she's older can I use sand now? Or what should we use? And, if you use sand, how do you keep it clean?
The other questions is: now do we need a longer UV light - the one we have is only about 2' long.
Thanks
