Have you decided to pet axolotls in your tank? Do you want to provide them with the best food? You need a brief guide on axolotl food containing what to eat and what to avoid so your pets can thrive happily. The good news, feeding this smiley salamander shouldn’t be overwhelming.

Axolotls are native to canals and lakes in Mexico. In their natural habitat, they eat small animals like insects, slugs, worms, small crustaceans, mosquito larvae, and smaller fish. This smiley creature even feasts on smaller salamanders they can find.

Teeth are present in axolotls but they don’t chew their food. When they find prey, they open their mouths widely, suck in water along with the prey, and swallow them. Rather than using their teeth to chew, they only use them to snap the food.

It makes sense that axolotls only feed on small food—so they can swallow it as a whole. Providing large food will cause trouble in their gastrointestinal tract, such as bowel obstruction which can be fatal. Gravel or pebbles can also cause impaction, that’s why aquarists need to avoid them in the tank.

In nature, axolotls don’t eat plants. If you find them snap down on one, there are some possibilities. First, your axolotls are very hungry. Second, these little creatures notice the motion of the plants and consider them as prey.

Now that you know what to feed your pet axolotls, it’s time to get to know how to feed them. As previously mentioned, axolotls have a set of teeth but they don’t chew or tear up prey. Rather they grip down on them and open their mouth to such smaller creatures.

Axolotls are carnivorous, which means they mainly eat smaller animals. Their diets are diverse but they don’t typically eat plants. Though they are not as picky as other animals, you can’t offer all food types to them. Here’s a list of food you definitely shouldn’t feed your axolotls.

1. Processed Meats

Processed meats are harmful not only to humans but also to axolotls. This type of food contains plenty of preservatives and harmful chemicals which could affect the health of your pets even in small quantities. If you want to see your pet grow healthily, processed meats shouldn’t on their diet list.

2. Raw Meats

Raw meats can be a potential cause of fungal infection. Unhygienic raw meat is prone to the contamination that can impact your pet axolotls negatively. To avoid unwanted occurrences, it is the best decision to keep your axolotls away from this food source.

3. Animals with Crusty Exoskeleton

Axolotls’ teeth are not designed for chewing or ripping up prey. Providing them with animals having a sturdy exoskeleton isn’t a wise decision because it will damage their teeth. Besides, a hard exoskeleton can also cause a digestive issue in your pets.

Mealworms, for example, are not safe for axolotls because it contains chitin that could cause discomfort in their digestive tract. The same is true for krill and other types of shellfishes.

4. Feeder Fish

Feeder fish isn’t a good option when it comes to axolotl food. They are a popular live food for captive animals like turtles and aquarium fish but not for axolotls. The reason is quite simple—they potentially spread diseases and parasites to your pets.

But if you insist to feed your axolotls feeder fish, there’s a simple alternative. Be sure to quarantine preys for at least 2 weeks before putting them into your axolotl tanks. This helps make sure they are healthy and they don’t contain parasites.

5. Dead Crustaceans

Dead animals could develop fungal and bacterial infections. If you want to feed your axolotls crustaceans, be sure they are life. However, this may be a big difficulty because most pets eat everything they find in the tank.

6. Plants

Axolotls don’t eat plants but they might bite ones in their aquarium only because they think it’s moving animals. Some plants won’t make your axolotls sick but they may cause indigestion. You may also find weird feces when axolotls eat plants.

Though some plants don’t cause serious issues, some others are toxic. Besides, leaving rotted plants in your axolotl tank could increase the level of ammonia as it decays. At high levels, ammonia can be toxic and incline the growth of bacteria.

When you captivate axolotls, you might be shocked for knowing that your pets eat each other. This frequently happens when you keep them in one aquarium. Axolotls can be cannibalistic at a certain stage, especially when they grow more than 6 inches.

However, their cannibalistic behavior isn’t assured. That means size isn’t the only factor that makes an axolotl a cannibal. A young axolotl raised with other axolotls at the same age is more likely to retain their cannibalistic behavior.

There are other reasons why your axolotls eat each other. In most cases, axolotls mistake the tails of their friends for live worms so they try to bite them. This also happens for aquatic plants. Axolotls can also bite their fellow’s limbs off.

Why Axolotls Stop Eating

Your axolotls can stop eating or reduce their food intake. There are several reasons for this issue, such as environmental change and the temperature of the tank. Both trigger a drop in axolotls’ metabolism that causes reduced appetite.

Constipation is another common reason why axolotls stop eating. If this is the possible cause, you may find other signs like they look ill and you rarely found their feces in the tank. Find a vet or seasoned axolotl owners to help you with it.

Axolotls are not picky eaters but providing nutritious food can help them thrive in captivity. Many aquarists believe that live foods are the best but frozen foods can be an option to offer. Just make sure they are safe and don’t contain the harmful chemical.
