...and the JD matures

[meanbestorque]

At about what size does the Jack Dempsey start hating the world? I'm curious because mine is currently 1.5 inches, but he's in with a few of my africans that are twice his size. I dont want to come home one day and find all my affricans that once picked on my JD to be dead.

When my JD was the same size as yours he was really aggressive, he would just attack any fish which went in his tank, I guess its mainly personality, but most will mature around 6in. I think

Mine became aggressive towards each other at just over 2" TL, about a month after they darkened up.
