Question: do axolotls need a bubbler?
Answer: Air pumps help oxygenate water for the Axolotl's gills. ... An air stone just doesn't have that much power, no matter how big your pump is to create enough current to stress your Axolotl. It is also nice to have an oxygenated tank so your Axolotl does not to go up to the top to breath as much since they do have gills.
