I love using black sand as I believe it makes everything in a tank stand out. I was thinking of using black coal slag for my axolotls as it looks exactly like this: black aquarium sand and I've kept it in my aquariums for over a year with sensitive bottom feeders and large mystery snails. From the description I've heard of an axolotls skin it sounds very similar to that of a snails to me. What do you think? I'm also curious to hear what colors of substrate you think make the axolotl's colors stand out the best.
