I think the term "stable" means that the fish is always colored up and not black. So if it goes from black to colored, it is not considered stable. I have a widebar that doesn't change color no matter what. You can change out all the water and decoration, chase him around the tank and he never drops his color.
I like the indo though, funny that you didn't know what he looked like till now! Good Luck
