What Fish Can Live With Axolotls: Best Tank Mates and Tips
You’ve probably stared at your axolotl’s tank and wondered if adding a few fish could make things more exciting for your aquatic buddy.
It’s tempting to imagine colorful swimmers sharing the space with your adorable amphibian. But here’s the thing: axolotls aren’t your average tank mates.
They have unique needs and quirks, which means you’ve got to be extra careful about who (or what) moves in with them. Let’s explore what fish can live with axolotls and how to make this setup work smoothly.
Why Axolotl Compatibility Matters

Axolotls are fascinating creatures with delicate skin, soft gills, and specific water needs. These factors make choosing tank mates carefully essential.
Axolotls can live up to 15 years in captivity with proper care, while their average lifespan is 10-12 years.
They’re carnivorous by nature, so small or slow-moving fish might end up as snacks. Meanwhile, aggressive fish could nip at your axolotl’s gills, causing stress or injury. Balancing these dynamics is key to a peaceful aquarium.
Key Factors to Consider
Before adding fish to your axolotl’s tank, think about the following:
- Water Temperature: Axolotls prefer cooler water (60-64°F). Most tropical fish won’t thrive in these conditions.
- Behavior: Aggressive or overly active fish can harm your axolotl. Look for calm species.
- Size: Any fish small enough to fit in your axolotl’s mouth is at risk of being eaten.
- Tank Setup: Provide hiding spots for both fish and axolotls to reduce stress.
Now that you know what to look for, let’s dive into specific fish options that might work.
Fish That Can Live With Axolotls
Some fish can share a tank with axolotls if you manage the setup well. Here are the best options:
White Cloud Mountain Minnows
White Cloud Mountain Minnows are hardy fish that tolerate cooler water, making them a popular choice. They’re small and peaceful, so they won’t bother your axolotl.
In the wild, axolotls generally live only 5-6 years, primarily due to predation and habitat degradation.
However, there’s a catch—they might become an easy snack. To minimize this, keep a larger group (6 or more) to reduce the chances of individual fish being targeted.
Guppies
Guppies are another possibility, especially since they breed quickly. This can create a steady food source for your axolotl if some get eaten. Stick to feeder guppies rather than fancy varieties, as they’re hardier and less expensive.
Zebra Danios
Zebra Danios are fast, active fish that thrive in cooler temperatures. Their quick movements can help them avoid becoming axolotl snacks. However, their energy might stress out your axolotl if the tank doesn’t have enough hiding spots.
Endler’s Livebearers
Similar to guppies, Endler’s Livebearers are small, peaceful fish that can coexist with axolotls. They tolerate cooler temperatures but may reproduce rapidly. Keep an eye on population control to prevent overcrowding.
Tips for a Successful Mixed Tank
Creating a harmonious environment takes planning. Here’s how to make it work:
Maintain Proper Water Parameters
Axolotls need cool, clean water with stable conditions. Regular water changes and a quality filtration system are crucial. Use a thermometer to monitor temperatures daily and ensure it stays in the ideal range.
Provide Ample Space
Crowding can lead to stress and aggression. For a mixed tank, aim for at least a 20-gallon tank (bigger is better). Add plants, rocks, and caves to create hiding spots and reduce stress for both fish and axolotls.
Adult axolotls typically grow to about 25 cm (10 inches) in length, though some can reach up to 12 inches.
Monitor Interactions Closely
Observe how your axolotl and fish behave after introduction. If you notice signs of stress—like gill curling in axolotls or fin nipping in fish—consider separating them.
Feed Strategically
Axolotls are opportunistic feeders, so keeping them well-fed can prevent them from targeting tank mates. Offer a variety of foods, like pellets, earthworms, or bloodworms, to keep them satisfied.
Fish to Avoid
Not all fish are axolotl-friendly. Here’s a list of fish you should avoid:
Goldfish
Goldfish might seem like a good fit due to their cooler water preference, but they’re a terrible choice. They produce excessive waste, which can harm water quality, and they’re notorious for nipping at axolotl gills.
Betta Fish
Betta fish are territorial and aggressive, making them incompatible with axolotls. They’ll likely attack or be attacked, causing stress or injury.
Cichlids
Cichlids are colorful and eye-catching, but they’re too aggressive and thrive in warmer water. This makes them unsuitable for axolotl tanks.
Plecos
Plecostomus fish might seem helpful for algae control, but they can latch onto axolotls, injuring their delicate skin.
Other Tank Mate Options
If you’re unsure about adding fish, there are other creatures you can consider:
Snails
Snails like mystery snails or nerite snails can coexist with axolotls. They’re slow, non-aggressive, and help with algae. Just make sure your axolotl doesn’t mistake them for food.
Shrimp
Ghost shrimp or Amano shrimp can work as temporary tank mates, but they’re often seen as snacks. Add them if you’re okay with replenishing them regularly.
Aquatic Plants
Adding live plants like Java moss or Anubias can enhance your tank without the challenges of fish. Plants also improve water quality and provide hiding spots.
Setting Up the Perfect Tank
Here’s a quick checklist to ensure your tank is ready:
- Tank Size: Minimum 20 gallons for a mixed setup.
- Water Temperature: 60-64°F.
- Filtration: Use a low-flow filter to avoid stressing your axolotl.
- Substrate: Sand or bare bottom (avoid gravel, as axolotls might accidentally ingest it).
- Hiding Spots: Add caves, PVC pipes, and plants for both fish and axolotls.
How to Introduce Fish to Your Axolotl Tank
Introducing new fish requires patience. Follow these steps:
- Quarantine New Fish: Before adding them, keep fish in a separate tank for at least two weeks to check for diseases.
- Acclimate Slowly: Use the drip method to gradually introduce fish to the tank’s water conditions.
- Monitor Closely: Watch interactions for the first few days and be ready to remove fish if needed.
Benefits of a Mixed Tank
Adding fish or other creatures to your axolotl’s tank can be rewarding. It creates a dynamic environment and provides visual interest. Just remember, your axolotl’s well-being comes first, so any additions must fit their needs.
Final Thoughts on Axolotl Tank Mates
Creating a mixed tank with axolotls and fish can be tricky, but it’s not impossible. Stick with cool-water species like White Cloud Mountain Minnows or Zebra Danios and avoid aggressive or territorial fish. Prioritize your axolotl’s comfort by maintaining proper water conditions and providing plenty of space.
