Axolotl in planted tank
I want to convert my planted tank to an axolotl tank in the future and have a few questions about them.
1. Is it ok to inject co2 and dose ferts with axolotls?
2. My tank is open top so how far should I keep the water level to be safe?
3. Are plants such as crypts ok at low water temps like 16c-18c?
Thanks in advance
