Great color is one major difference between wilds and captive breed they also tend to grow a little faster and are usually more aggressive
I've had a breeding pair of grammodes bought as fry from at the ACA in Wisconsin. Other than when protecting their fry, or making a quick dash to the surface for food, they are invisible. Dithers are killed over night. When I got them there were 6, saved one other, but they are merciless eradicators of anything that ventures into their territory.
