What Algae Eaters Can Live With Axolotls: Best Tank Companions Explained
Owning axolotls feels like being part of a special club. They’re fascinating, unique, and require a little extra care to thrive. You might be wondering how to keep their tanks clean without stressing them out. Algae can creep up, and scrubbing the tank isn’t always fun.
Adding algae eaters sounds like a great idea, but you’ve got to pick the right ones. Not all algae eaters will get along with axolotls, so it’s important to choose wisely.
Let’s talk about what works, what doesn’t, and how you can find the perfect tank mates for your little aquatic buddies.
Why Choosing the Right Algae Eaters Matters

Axolotls are delicate creatures with soft skin and a calm temperament. Some algae eaters are too active or aggressive, which can stress them out or cause injuries. Others might compete with axolotls for food or nip at their gills, which are very sensitive.
The pH level of the water should ideally be maintained between 6.5 and 8.0 for axolotls to thrive.
Finding algae eaters that are compatible with axolotls is crucial for keeping a peaceful, healthy environment in the tank.
Key Factors to Consider Before Adding Tank Mates
It’s not just about finding algae eaters that clean your tank. The algae eaters must also:
- Tolerate cooler water since axolotls thrive in temperatures between 60–64°F.
- Be non-aggressive to avoid harming your axolotl.
- Fit the tank size so they don’t outgrow their space or create overcrowding.
- Avoid competing for food, as axolotls may struggle with competition.
When you’re careful with your selection, you’ll keep your axolotls stress-free while maintaining a clean tank.
Top Algae Eaters That Can Live With Axolotls
Let’s explore the algae eaters that work best with axolotls. These creatures have proven to be peaceful, adaptable, and effective at keeping tanks clean.
Mystery Snails
Mystery snails are a fantastic option for axolotl tanks. They’re slow-moving, peaceful, and great at eating algae off glass, decorations, and plants.
- Why they work: Mystery snails thrive in the same cool water temperatures axolotls prefer. They’re also too slow to bother your axolotl.
- Tank tips: Make sure your snail has hiding spots, like caves or plants, to avoid accidental bumps from curious axolotls. Keep the tank lid secure since snails can climb out.
Nerite Snails
Nerite snails are another excellent choice for algae control. They’re small, efficient, and come in various colorful patterns.
- Why they work: Nerite snails are peaceful and tolerate cooler water. They won’t disturb axolotls and are great for cleaning algae off hard surfaces.
- Tank tips: Avoid overstocking nerite snails as they can lay eggs that don’t hatch in freshwater, which can clutter your tank.
A single axolotl requires a minimum tank size of 15 gallons, with an additional 10 gallons for each additional axolotl.
White Cloud Mountain Minnows
If you’re looking for a fish option, white cloud mountain minnows can sometimes work with axolotls. They’re small, fast, and not aggressive.
- Why they work: They tolerate cool water and won’t nip at your axolotl’s sensitive gills. Their small size also reduces the risk of them being mistaken for food.
- Tank tips: Keep a small school of 5–6 fish to reduce stress among the minnows. Monitor closely to ensure your axolotl doesn’t try to eat them.
Amano Shrimp
Amano shrimp are popular algae eaters that can coexist with axolotls under the right conditions. They’re small, efficient, and peaceful.
- Why they work: Amano shrimp tolerate cooler water and focus on cleaning algae rather than bothering axolotls.
- Tank tips: Provide plenty of hiding spots since axolotls might mistake the shrimp for snacks. Use moss, plants, or rock crevices for hiding places.
Algae Eaters to Avoid in Axolotl Tanks
Not all algae eaters are a good match for axolotls. Some are too active, aggressive, or simply incompatible with the cool water environment.
Plecos
Plecostomus (plecos) might seem like a great option because they’re excellent algae eaters. However, they’re a poor choice for axolotl tanks.
- Why they don’t work: Plecos are tropical fish that prefer warm water. They can also become aggressive, often nipping at the soft skin or gills of axolotls.
- Better options: Stick to snails or shrimp for algae control instead of plecos.
Ideal oxygen saturation levels in the water should be between 70% to 100% for optimal health.
Siamese Algae Eaters
While Siamese algae eaters are efficient cleaners, they’re too active and fast for axolotl tanks.
- Why they don’t work: Their high energy levels can stress axolotls, and they thrive in warmer water. They may also outcompete axolotls for food.
- Better options: Choose a snail species instead for a calmer tank dynamic.
Otocinclus Catfish
The small, peaceful otocinclus catfish might seem like a good idea, but they don’t do well with axolotls.
- Why they don’t work: They prefer tropical temperatures and may become stressed in cooler water. They’re also vulnerable to being eaten by larger axolotls.
- Better options: Consider shrimp or mystery snails for similar cleaning benefits.
How to Create a Balanced Tank for Axolotls and Algae Eaters
Adding algae eaters to your axolotl tank is just one part of the equation. You’ll also need to maintain a balanced environment to keep all tank inhabitants healthy and happy.
Tank Size and Setup
A larger tank reduces the risk of overcrowding and provides plenty of space for axolotls and algae eaters.
- Minimum size: Use at least a 20-gallon tank for one axolotl. Increase the size if you’re adding algae eaters or more axolotls.
- Hiding spots: Add caves, plants, and rocks so algae eaters and axolotls have places to retreat when needed.
Temperature and Water Quality
Consistently cool, clean water is essential for both axolotls and their algae-eating companions.
- Temperature: Keep the tank between 60–64°F. Use a reliable aquarium thermometer to monitor daily.
- Filtration: Choose a gentle filter that won’t create strong currents. Axolotls prefer calm water, and so do most algae eaters.
- Water changes: Perform regular water changes to remove waste and maintain water quality.
Feeding and Diet Balance
Algae eaters need their own food sources, even if they’re cleaning algae.
- Supplemental food: Offer algae wafers, blanched vegetables, or shrimp pellets for snails and shrimp.
- Axolotl food: Stick to high-quality pellets or frozen bloodworms for your axolotls. Feed them separately to avoid competition.
Monitoring Tank Behavior
Always keep an eye on how your axolotls and algae eaters interact.
- Signs of stress: Watch for hiding, reduced appetite, or erratic movements. These may indicate stress or aggression.
- Adjustments: If a tank mate isn’t working out, move them to a separate tank to keep your axolotls safe.
