so I have two juvenile Jack dempseys around 3 inches, and they are feuding. They have split the tank almost directly down the middle, one stays on the right and one on the left.
The color differance between them is crazy, the one on the left is light and looks like a regular dempsey. The one on the right is almost totally black. What the heck is the deal? other then the color everything is the same neither one is overly dominant or stressed.
any Jack dempsey keepers know what is going on?

One is dominant one is submissive

I have 2 jags. One is bright other is dark.
 
my experience at least....

my male jd goes super dark when he's courting or ready to brawl. The lighter one appears to be male and when mine is stressed he looks exactly like pic 1
 
You got it the Other way around.
umm...no

light=stress
dark=dominance

Only my experience. Yours may be different but when my jd is light colored something is usually wrong or there has been change in the environment, such as a water change. if I feed live foods or its time to spawn or brawl, mine gets dark.
 
ummm darker coloring as opposed to regular coloring...hmmmmm
regular coloring means that one is feeling normal.
any change in coloring means that something has changed with the fish's mood. doesn't that make sense to you?
darker showing stress barring/patterns means stressed.
 
What I learned was that fish that are pale white(not regular) would show stress... a darker shade, while it does show change doesn't exactly mean that it's stressed.
