Chameleon stressed?

[Pascal21]

Sorry if this has been answered im new to the forums but have come here often to read other threads. I recently purchased my baby veiled about 3 weeks ago and everything has been fine up until 2 days ago when I purchased new vines to put in his enclosure. Before I put those in everything had been fine, eating and drinking, I have been dusting all feeders including gut loading, temps are good and UVB lighting as well. Only after I added these new vines has he stopped eating, drinking and has more often then not been a dark black/brown. Today I removed the new vines and cleaned out the cage. He was a Normal
Color for about an hour then turned black and moved as fast as I have ever seen towards where he knows I open the cage from seeming like he wanted out. I'm not entirely sure what to do as I don't want to lose my Cham :/

TLDR; had Cham for several weeks, introduced new vines, Cham turns black stops eating and drinking, remove new vine after 2 days. still acting stressed.

Probably just stressed is all. You added something new which stressed him out a little. He would bounce back in a few days normally. And since you took it back out has probably been re stressed. I know if I add or move anything in my guys cage he gets very grumpy and stressed. I just recently rearranged my room to add more space and to give my guy more open space near him. Took him a few days to adjust but went back to normal very quickly.

maybe it is too cold inside or something that scarres him inside the cage?

Thanks for the input! This is my first Cham and I had done months of research prior to purchasing one! I assumed as much that he was just grumpy and stressed, it just worried me because he's on a hunger strike now!
Do you think I should re-add the vines or keep them removed as I know every Cham is different and I felt like they gave him more places to hide and feel safe!
And the cage is around 85-90 degrees in the warmer side and the colder is 75-80 , it varies, his basking spot is usually around 86-88. I have a digital thermometer to take readings!
