I was surfing Datnoid threads at work from other forums today (yeah it gets pretty boring selling jewelry lol) and one of the old threads I saw stated to try keeping them in white background tank to brighten them up. I mean I guess it could make sense that they'd go darker in a dark tank to try to camouflage so why not go brighter in a bright tank. Any thoughts on this? Anyone here try keeping their tigers in a bright tank?
