You have to post some pics! I commented on your other thread to welcome you. If you want to determine the sex of a veild you check the back feet. The back heel has a little point called a tarsal spur. Only the males have it. If you are not sure, post a pic of the back feet and we can tell you. When they are that young, that is really the only way to tell the sex as the colors don't start coming in to later and then you can distinguish sex. The advice you were given above is good. Waterfalls are really frowned upon in the chameleon world. Red lights too. Red is not a natural color as it does not replicate the sun. Most, if not all of us, use white bulbs, and just an ordinary white housebulb will do. One 5.0 uvb light(tube style preferred). You could have more than one basking spot if your cage is large enough. You chameleon can take temps down into the 50's so no heat unless it gets this cold. If so, you can use a ceramic heat emitter bulb which does not produce light, but just heat. It can be screwed into one of the light domes. Also, be careful of making it too humid and damp as chameleons are prone to respiratory infections. Your humidity should not stay constant, but rise and fall.
but there are a few things that you could change. You really should not have a fountain in the cage because 1) your chameleon could drown 2) it is a great place for bacteria to grow and unless you are going to clean it out every day it could make smaug very sick. Also about the lights what UVBs are you using (ex: 5.0 ) and to much UVB is not good. There should be any light on at night( even the red) chameleons are very sensitive to light and it will mess up their sleep. If you are worried about him getting cold then you could use a space heater run though the night like I do or get a light bulb that gives of heat but no light. At night the temp could drop down to the 60s and he will be ok. You really should read the care sheet
