i have a red empress thats about 2 1/2 - 3" and isnt shown any coloring besides a lil orangeish red on his fins. When should he color up and loose all his black blotchs on his body and his bar
I have one at about 3.5" with still no color. It's definitely a male and still... Very little color. He is not the most dominant fish in the tank which can play a role in them coloring up...
