I noticed a lot of african keepers use white substrate. Doesn't this cause the fish to have less vibrant colors? Doesn't the fish poop and aglae show up more easily this way?

i have seen tanks with light sand and it seems to bring out the fishs color ok. Now after i have black sand in all my tanks i think light sand looks better. Hey sinister i forgot you were on here. recognize you from cichlid forum. you have more posts than me there too.lol
