I currently own a 29 gallon aqaurium, housing Brachygobius sp. among other brackish fish. I am planning on moving these fish to a 55 gallon planted. As a lot of these fish have black colorations, what should be the color of the background and subtrate? I was thinking black as I will have some rich green plants such as java moss and java fern ect etc. The "driftwood" is old fallen branches (they actually look quite stunning) from a tree in my yard. The wood turns a kind of brown blotchy color with some areas a light tan, some a coffee color ect etc. Do not worry about the wood, I use the bleach recipe the make it safe for aqauriums, and have done it for years without a single problem or change in water chemistry. If you use brittle wood it seems to hold quite well when submerged.
