I'm setting up my new dat tank and I'm trying to decide on the background color. I am thinking of going blue instead of the usual black. I have heard from some others that a lighter color background may produce more stable dats. Not sure if this is true or not. Currently I have them in a black background tank and only a few (5 out of 14) are stable all the time. Does anyone have any first hand experience in changing background colors on dat tanks? Was there any change in the stability of the dats? Thanks for the help.
