so, I typically prefer a mixed browns, natural looking substrate... but I have a few more unique substrates... I have one tank, that I like the look of, that has jet black sand... except when something else gets on the sand... I have 2 pieces of ceramic media that fell out of a planter, and they stand out like a sore thump, against the black sand... I also have a tank, that has white sand, and several pieces of what looks like carbon, are on it... both of these tanks would be a pain to tweezer out the offending pieces... and as much as I like both, I'm temped to stay with the natural mixed tones, of which both of these would blend into, and not stick out so much...
