I know this has been brought up a lot but wanted to get a opinion. Right now the back of my tank is painted black. I thought about scraping it off to see if my discus would lighten up my bss is always dark and so are my rt's. So my thought is scrap the black off and maybe put a different color like a green or blue to try to help them be more comfortable. Fish stock includes bss rt colbolts pigeon blood tefe and white spotted red dragon
