I noticed that several bichir keepers put their bichirs in blue tank with red bottoms or red gravel and I'm wondering why. Does doing so brings out the colors and contrasts of bichirs? I noticed the lapradei in 2010 Bichir Update displays high-contrast and it's resides in a blue tank as well. If a wild-caught lapradei is placed in such a tank, it should display high-contrast as well?
