Black blemishes

[VeiledBunta1984]

I have recently had my first chameleon.
He is a Veiled chameleon 2.5 months old.
Im worried about the black blotches on either side of him.
His setup is as follows:
Viv: 100 gallon Flexarium which is out of high traffic and the top is about 6ft from the floor
Lights: 2x 24" Reptisun 5.0 which sit on top of his flex
8am-8pm
Heating: 150w ceramic heater & 75w Heat glo bulb
Temps: 86-90F at basking spot 70-80F elsewhere.
Humidity:40-60%
Food: Size 4 Crickets which are dusted with D3 (Tues,Fri.) Without D3 (Weds,Sat). Multivitamin (Mon,Thurs)

I have attached a pic of his spots and the viv setup

Your going to need some clearer pictures can't tell in those.

If you're referring to the three marks on the middle of his side, I'm pretty sure those are just his coloring. They are very typical of a veiled, I believe.

Are you sure he's 2.5 months old? He looks bigger than that. Although I guess there isnt much of a reference to tell from.

Lastly, you should adjust your supplementing schedule. you're using all the right supplements, but you should be using Calcium w/out D3 almost everyday, Calcium w/ D3 once a week, and the multivitamin only once a month.
