Black Axolotl Substrates?

[ThoseNewtsTho]

Fine black aquarium sand will be okay, but the option I would prefer is siliconed down slate tiles., but this is only really if setting up a new tank, I've also heard of people using barebottom tanks and they painted the underside of it or put decorative wallpaper under it.

I have black sand in one of my Axolotl tanks. I think it was the Petco brand and the Axolotl was about full grown, so I wasn't too worried about ingestion issues.

I've found that with some brands of sand (and gravel) the color leaches off, so be careful.
