Axolotls: Finding the right substrate?

[Endless Ocean in My House]

I know axolotls will digest any substrate too small. I found those clear pebble-like stones that I thought were big enough, but I'm not sure. I do not have an axolotl yet. The pebbles I have are about two centimeters in diameter.
Are those too small?
If so, what else can I put down?

Most axolotl owners would probably have a bare bottom aquarium.

If yor axy gets big enough those could get consumed easily. I started off with the same then moved on to large pebbles but after discovering how messy the little critters are (poo will end up under stones no matter how vigilant with cleaning you are) I switched to nothing. A bare bottom can look really pretty if theres a background on your tank as it will give off a mirrored image so dont be put off! . Oh and get a turkey baster for their poop, I guarantee it'll be your new best friend!

Thanks! I am actually using sand though. I read they needed something to grip on.

I've had my axolotl for a few months, and I use sand as well.

Hey, Liz, how do you keep an airstone from making a current that will disturb their gills?

 

[Liz_H]

I don't have an air stone in his tank. I use an aqua clear hob filter, and keep the water level up pretty close to where the water pours out (foggy brain atm and can't think of the proper word) so there isn't much movement in the water...

Interesting! Thanks so much.

 

[Liz_H]

You're welcome.

I use pieces of flag stone that I boiled to make sure they were clean. It's easy to fit them in the bottom of the tank and easy to remove and clean. I think the rule of is that if it fits in their mouth, they'll eat it

Is flag stone the same, or similar to, slate?
