Death Pony;3190893; said:If you get an RTG for the big tank, I suggest some large Asian barbs and a medium sized Mystus or other Bagridae catfish. A sprinkling of black sand mixed in with the white will look good, or some nutrient rich soil for growing plants.
gna sprinkle black sand to a ratio of about 1:6(b:w) and add large black gravel round the sides
