says what it says in the title, i have a black back ground painted on the tank can't change that, i was going to go with black sand, onto of black substrate, but then I'm thinking to much black?, i have mini landscape rocks, which are Light, and some small pieces of bog wood, and this tank will be HEAVILY planted, so would black sand and black back ground compliment the green n colours of plants along with the light landscape rocks? or will it just be to much dark, bare in mind the fish i will be putting into the tank are also light, neons, danios, blue eyed orange BN pleco, and salt n pepper corys
