Hey Guys wanted to get some opinions on a background color for The 55 Gallon Tank. Its going to house 6 Tiger Turquoise Discus. I've heard people talk about how lighter colors make the discus look better, but I'm impartial to the black backgrounds. Every single tank in my fish room is black lol. I was thinking maybe a blue? Choice are Black, Light blue, white or Darker blue. I'm using lighter pool filter sand. Would love to hear opinion... wish there was a vote template.
