The colour change is not caused by stress with Barras.
They will change colour allll the time, depending on mood, light, what they just ate and surroundings... can be caused by heaps of things, but most of the time its not stress or water parameters.
If he is the dominant fish in the tank or on his own he will display different colours alot.
