How to choose the best filter for axolotl?

An axolotl should be in a tank holding 15 – 20 gallons. Thus, the best filter for an axolotl tank should well-clean this tank size and create a good water environment for an axolotl. Choosing a filter for an axolotl tank should not miss the below key points.

  • A good filter with the adjustable flow to get water highly oxygenated and crystal clear: This is one of the key points for a good filter for axolotls. Axolotls have very sensitive skin since they get water and oxygen through their skin contact. Thus, keeping the tank water in a highly oxygenated and clear situation is very important. The flow rate should be kept slow so it is also important to have a flow control to adjust the current and do not make your axolotl stressful. 
  • A filter that will not take up much space of axolotl in a tank: An axolotl is usually from 6 to 18 inches long in adult size, thus, keeping a big space for them to explore is important. Both a hang-on-back or a canister filter could do this. However, a hang-on-back filter should come with a good top lid to assure that the axolotl will not jump out of the tank and die.
  • A filter that is convenient in changing media: A good and complete filtration system is important but an axolotl tank needs weekly water change, thus, the convenient filter will help aquarists save more time.
  • A filter could run quietly: This is important for most aquarists because you do hope to enjoy water life with peace of mind when coming back home more than the busy life outside. Thus, a noisy filter will normally trouble you the most.


What is an axolotl?

An axolotl, also known as Mexican walking fish, is a kind of salamander that can be various in colors like black, gray, gold, and white. They look very exciting and rather hardy. Thus, they could be a good option for aquarium starters. They are unique among amphibians because they do not undergo metamorphosis; instead of going to the land at the adult time, they remain aquatic and gilled their entire life.

  • Common names: Axolotl, Mexican walking fish
  • Originated from: lakes in Mexico City
  • Scientific name: Ambystoma mexicanum
  • Adult size: Between 6 and 18 inches long, though over 12 inches is rare
  • Life expectancy: 10 to 20 years on average

What are the most common notices when taking care of an axolotl?


  • An axolotl needs at least a 15 to 20-gallon tank.
  • They enjoy a solitary life.
  • The tank should be kept away from bright sunlight.
  • Tank temperature should be around 57 – 680F (14 – 200C).
  • If there are gravels at the bottom of the tank, it should be coarser than axolotl’s head or it could be ingested and get obstructed.
  • If the tank is using a filter, you could do 20% of water change weekly, or else, you should change 20% tank water daily.


  • In the natural world, snails, worms, crustaceans, small fish, and small amphibians are usually food for axolotls. In aquatic captivity, you could feed them by a variety of brine shrimps, small strips of beef or liver, earthworms, bloodworms, worms, other frozen fish foods, and commercial fish pellets as well. Substrates are very important to axolotls because just like other salamanders, they tend to ingest the bedding material together with food.


  • The safest water for axolotls is bottled water which has been treated by reverse osmosis. If you are going to tap water, keep in mind that you should let the water sit for at least 24 hours for the chlorine to dissipate and evaporate; or you could buy special dechlorination drops at the local pet store and treat them before using.

Handling an axolotl:

  • You should never handle an axolotl by hand because of their very sensitive skin. Consider using a net that could gently catch them without affecting their skin.

Should I give companions to my axolotl?

Axolotl tends to eat other pet fishes and the fish may also nip at axolotls. Juvenile axolotls or even adult axolotls can be cannibalistic toward one another. Thus, it is best to keep them alone.
