I think it would look good especcially if you got black and white fish, I have 55 painted black and i have small zebra eel(black and white), black and white striped damsels, white hermits crabs,black niger trigger, and i think the black and white theme looks great!!!I have crushed coral bed but i think black sandbed would look just as good. Trying to think of more black and white fish that look cool for the theme as the tank is still looking kinda bare but its a cool start!!
