do chameleons stress eachother out even if there in different cages but they can look at eachother

yes very much so.

Yep what the chamman said

should i put a barrier so they dont see eachother

yeah that would probably be the best idea

use a plastic sheet or a piece of sheet metal or some cardboard.

you can buy a rainforest backdrop of plastic which will not only look good but do a good trick.

make sure it is not reflective because seeing themselves will also stress them out

tru one time i had 2 veilds and one grew great but the other was like a dwarf i think it was dew to stress from the other one cause i didnt have a barrier

a galvonized metal would work.
