Axolotl vs. Other Aquatic Pets: A Comparative Guide

Are you considering introducing an aquatic pet into your home but not quite sure which one is the right fit? You've probably heard of popular options like betta fish, goldfish, or turtles. But have you considered the axolotl? This unique amphibian, known for its fringed external gills and ability to regenerate its limbs, is increasingly popular among aquatic pet enthusiasts. In this article, we'll compare axolotls with other common aquatic pets to help you make an informed decision.

What is an Axolotl?

Axolotls (Ambystoma mexicanum), also known as Mexican walking fish, are salamanders native to the Xochimilco lake complex near Mexico City. Despite being referred to as a 'fish', they're actually amphibians! Axolotls are known for their fascinating characteristics, such as their perpetual state of larval development, which allows them to live fully aquatic lives.

Axolotl vs. Betta Fish

Betta fish, also known as Siamese fighting fish, are popular pets due to their vibrant colors and relatively easy care requirements. Like axolotls, they require a specific range of water temperature (around 78-80°F for Betta fish). However, bettas can survive in smaller tanks than axolotls, who need at least a 20-gallon tank due to their size. Both animals are carnivorous, but axolotls require a diet of protein-rich food like worms, whereas bettas can subsist on high-quality pellets or flakes and occasional treats of live or frozen food. In terms of lifespan, axolotls have a longer life expectancy, with a potential to live up to 15 years compared to betta fish's average of 3-5 years.

Axolotl vs. Goldfish

Goldfish are perhaps the most iconic of all aquarium pets. They are cold-water fish and prefer temperatures between 65-75°F, cooler than the axolotl's preference for 60-68°F. Goldfish can grow to be quite large, requiring a tank of 20 gallons or more, similar to axolotls. Unlike axolotls, goldfish are omnivores and eat a mix of plant matter and small crustaceans or insects. In terms of lifespan, goldfish can live for many years with proper care, with some varieties known to live up to 20 years or more.

Axolotl vs. Aquatic Turtles

Aquatic turtles, such as the red-eared slider, are another popular choice for aquatic pets. Turtles require a different type of habitat than axolotls, including a basking area outside of the water. Turtles are omnivorous and eat a diet of both plant and animal matter. Turtles can live for many decades, making them a long-term commitment. Additionally, turtles can carry salmonella, which can be a concern for households with young children or immune-compromised individuals.


Each aquatic pet has its unique needs and characteristics. Axolotls, with their quirky appearance and fascinating biology, make for a unique and rewarding pet experience. They do require a specific environment and diet, but with proper care, they can thrive in a home aquarium. Whether you choose an axolotl, a betta fish, a goldfish, or a turtle, remember that all pets require a commitment to their health and well-being. Happy pet-keeping!
