Size substrate

[Roxee592]

Hello! I got my first axolotl and I am currently letting the tank cycle before I put him/her in and I’m wondering about the substrate I put in the tank. It is sand but I don’t know if it is fine enough. Would the sand be fine if it is smaller then the axolotl’s waste (Incase it did get sucked up)?

In general you either want sand as it passed through their digestive system (yours is probably fine if your axolotl is not a larvae) or pebbles larger than their mouths so that they can't ingest them. They are perfectly fine without any substrate as well. Makes cleaning the tank much easier. :happy:
