Currently I have a (maybe 6in?) flowerhorn that I got about 3 weeks ago. He’s in a 37gallon tank and I just bought a 65 gallon I’m going to transfer him to. I want the new tank to look a bit more modern and I want a black background but will this affect his colors too much? He’s a fireman’s dream so I’m not sure if it would affect his specific colors or not. I plan on white sand though. Thanks! Here’s a pic of him for reference
