In addition to what has already been said...
You’ll need to use a multivitamin and a calcium with D3, one feeding every other week for each. Or, you could get the 2 combined in Reptivite with D3 and use that for one feeding every other week.
Chams like variety of feeders. Attaching feeder and gutloading sheets for you. You should only be feeding once early in the day. She looks a bit older than 2 months. I’d guess she’s more like around 4 or even maybe 5 months old.
Also attaching plant and lay bin graphics too.
Live plants are best, especially for veiled. They nibble at their plants and have been known to eat a fake leaf and become impacted, which can be life threatening. I use the fake plants on the outside of my enclosure doors to give extra privacy. Pothos is perfect for chams.
No idea what a watering tree is, but if it’s like a fountain, it needs to come out. The best way to provide fresh water is thru misting/spraying. Usually mist for at least 2 minutes early in the day and later in the evening. You can use a dripper for mid day or add another misting session.
You’ll need a minimum 2x2x4’ (or equivalent) enclosure for her very soon.
When you say dual lighting kit, I assume it’s a double dome and the uvb is a screw in bulb. Unfortunately these are able to provide adequate uvb levels only 2-3” away and have been the cause of many cases of metabolic bone disease (mbd). You need a long T5 ho fixture with a 5.0 uvb bulb. One like this is perfect.
https://www.pangeareptile.com/store/arcadia-prot5-uvb-kit.html I prefer Arcadia bulbs as they are good for a year, vs only 6 months for other brands. The uvb needs to as long as your enclosure is wide. I’d suggest having a lights on/off schedule of 12 hours.
As I said earlier, it looks like your little girl may be receptive. If so, she will soon be needing a lay bin. It’s pretty simple to put together. Get at least a 12”wide/long (bigger is a bit better) and fill it to at least 6” deep with play sand moist enough to hold a tunnel. Provide a few ways in/out. I suggest leaving it in her enclosure permanently to avoid guessing when she needs it and stressing her with putting a new item in. When she needs it, it’s there and she’ll find it. When she does reach that point and has started digging, she’ll need absolute privacy or she won’t lay.
I hope we’ve been of some help. Do ask as many questions as you need.
