I recently took my Jackson chams outside for some sun. (one at a time, because I find it hard to keep up with both of them, although they have never fought with each other, but they are very active!) I noticed one of them (they are both females) turned a very dark color, as though she was stressed, but after a few minutes, she turned back to her normal color, and just sat there on my hand, sunbathing I guess. When I took The other cham outside, she sat there on my hand, and completely turned on her side, basically flat.. I thought she was dying?? (i am a first time cham owner, and am new to this) I was just wanting some advice as to if I'm doing everything okay, and if both chams we're showing normal behavior?
