Axolotls, also known as Ambystoma Mexicanums, are amphibians found in the lake of Xochimilco near Mexico City. An axolotl's life expectancy is of 10-15 years of age in captivity, provided they are given adequate care. It's essential to provide a suitable tank for your axolotl to thrive and grow. This wikiHow article will show you how.

Setting Up the Tank

1
Find a suitable tank. Axolotls need plenty of room to grow, as they generally reach a foot long in length. A 20 gallon long is your best option if your axolotl is a baby in 1-5" in length. If your axolotl is over 6", you will need to upgrade the tank to a 30 or 40 gallon.
- Axolotls prefer length to swim and not necessarily much depth to dive deeper or shallower. Long versions of tanks above a 20 gallon work best.
2
Purchase the right equipment. To set up an axolotl tank, you will need a gravel vacuum, thermometer, and a sponge or bubble filter. Remember, axolotls prefer a temperature between 60-64°F.
- While you shouldn't use gravel in the tank due to the ease of swallowing rocks, you should purchase a gravel vacuum to sift through the sand and suck up any waste.
- A sponge filter is best, as they suck in particles to allow for the growth of beneficial bacteria while producing oxygenation and circulation to pick up most of the loose debris.

Axolotls must not be in a high flow area because it will cause them stress, and they will die. They like to walk on the bottom of the tank with minimal current.

Buy your axolotl accessories for their tank. Your axolotl will need sand to lay at the base of the tank and decorations, such as rocks or caves.
- Sand of any color that is safe for axolotls will be suitable, but it is best to have a bare bottom tank for baby axolotls, as they might accidentally ingest substrate.
- Rocks (as big as the axolotl's head), fake plants, or plastic caves are a few examples of decorations you can plant in your axolotl tank. Make sure the decorations in the tank are not sharp, as they could easily scratch and injure your axolotl.
- If you are using rocks, place the decorations in a pattern and provide caves for shade because of their sensitivity to light. Rocks can often-times be stacked or staggered.

Axolotls are fascinating creatures, and setting up their tank is a crucial part of their care. Remember, the tank is their world, so it needs to be as comfortable and as natural as possible. Provide plenty of hiding spots and make sure the water conditions are just right. Axolotls are not just pets, they are a commitment and a journey into a fascinating corner of the natural world.
5
Add water to the tank. A water conditioner is a necessity due to the traces of chlorine in tap water, which is toxic and will kill freshwater aquatic animals like axolotls. The water conditioner eliminates chlorine through chemical reactions.
- Different products may have different instructions on how much to use when putting the conditioner in.
6
Cycle the water before placing your axolotls inside. Cycling the water should be done to convert ammonia to nitrite to produce beneficial bacteria that will help maintain the fish economy.
- A tank is cycled by first adding ammonia, such as household ammonia, and allowing the tank to run and build up beneficial bacteria in the filter and substrate. This process takes 6 to 8 weeks on average, so make sure you prepare in advance.
- The tank will be cycled once the water conditions level out and become consistent.
- The pH of an axolotl tank should be anywhere from 6.5 to 8, but 7.4 to 7.6 is ideal.
7
Test the water quality. Even though the water may look clean, the water quality could still be unsuitable for your axolotls to live in. Check the water quality weekly using a water tester kit.
- Compare the water to suitable charts to see if it is safe for your axolotls to live in the water.

Adding Your Axolotls to the Tank

1
Pick out your axolotl. There are different types of axolotls to choose from, with five main types that are commonly sold. This includes the Wild Legalistic, White Albino, Golden, and Melanoma.
- There are more types of Axolotls, especially when crossbred.
2
Do not house axolotls with other fish. Axolotls do not co-exist peacefully with other fish. Because axolotls have very poor vision, they will bite at any movement. There is a great chance your axolotl will end up eating the fish in the tank.
- For the fish and axolotl's safety, it's best only to keep axolotls of the same size in the tank.
3
Acclimate your axolotl. When coming home from the store with your axolotl, you should start by putting them in the water with the bag and allow them to acclimate for 15-30 minutes.
- After the time is up; you can safely open the bag and let your axolotls free in the tank.
- It's important to allow your axolotls to transition instead of adding them straight to the tank. Otherwise, you can put them into shock and cause fatality if the water temperatures are too far apart.
4
Provide your axolotls with food. Axolotls are carnivores; they eat frozen or dried bloodworms, night crawlers, and other insects, and thawed calf liver. Feed your adult axolotl once every 1-2 days.
- Make sure you have a dish to drop their food into the tank to help your axolotls locate the food to prevent it from getting lost or wasted in the substrate.
5
Monitor your axolotl in their tank. Each new axolotl parent should observe their tank every hour to ensure their axolotl is acclimating well to its new environment.
- Look for any behavioral changes to indicate something may be wrong. Observe your axolotl's eating habits, as a declined appetite is usually the first sign of illness.
6
Clean the tank frequently. Axolotls excrete quite often. This waste has to be cleaned up to prevent build-up, as decomposition can cause ammonia and nitrate levels to spike.
- Clean your tank using a gravel vacuum. Even if you do not use gravel, the vacuum helps keep the bottom of the tank clean and assists with water changes.
- A clean sponge can help clean any algae build-up on the side of the glass. Keep your tank out of direct sunlight to prevent algae buildup.
- 20% of water per week should be changed to maintain water conditions.

Question

Is it okay to feed your Axolotl pellets?

Nicole

Community Answer

Yes! It is okay for axolotls to eat pellets, but they do prefer worms like night crawlers, brine shrimp, pieces of chicken, and sometimes insects. But do not use bloodworms as an everyday meal, bloodworms are only snacks to eat here and there.

Axolotls are illegal in Australia, so unfortunately, you can’t buy one there.

If you don't cycle the water, your axolotl may get very sick and die within weeks.

Axolotls take lots of maintenance and have a life span of up to fifteen years, so make sure you are fully dedicated to this long-term commitment.

Do not add any other fish to the tank except axolotls.
