Do Axolotls Hate Fish? The Truth About These Amphibians
Do axolotls hate fish? Not inherently, but compatibility issues and potential dangers often exist; therefore, keeping them together is generally not recommended. Careful consideration of their natural behaviors and tank conditions is crucial.
Understanding Axolotls: More Than Just Cute Faces
Axolotls, those perpetually smiling amphibians from Mexico, have captivated the world. Their unique appearance, neotenic nature (retaining larval features throughout adulthood), and regenerative abilities make them fascinating creatures. However, their care requirements and potential interactions with other aquatic animals are often misunderstood. Understanding their needs is paramount before considering tankmates.
The Axolotl Diet: Carnivorous Ambush Predators
Axolotls are carnivorous ambush predators. In the wild, they feed on insects, crustaceans, and small fish. In captivity, their diet typically consists of earthworms, bloodworms, and specially formulated axolotl pellets. While they may not actively “hate” fish in a conscious, emotional sense, their predatory instincts mean they will readily eat fish small enough to fit in their mouths.
Why Housing Axolotls with Fish is Risky
The primary reason keeping axolotls and fish together is problematic lies in the inherent risks to both species. Here’s a breakdown:
- Predation: As mentioned earlier, axolotls are predators. Smaller fish are potential prey.
- Nipping: Conversely, fish, especially those with long fins or vibrant colors, may nip at an axolotl’s gills or limbs. This can cause stress, injuries, and even secondary infections in the axolotl.
- Water Parameters: Axolotls require cool, clean water. Many fish species prefer warmer temperatures, creating an unsuitable environment for both.
- Competition: Even if the fish are too large to be eaten, they may compete for food, stressing the axolotl and potentially depriving it of necessary nutrients.
Ideal Tank Conditions for Axolotls
Creating the right environment is crucial for axolotl health.
- Temperature: Between 60-68°F (16-20°C) is ideal. Temperatures above 72°F (22°C) can cause stress and make them susceptible to disease.
- Water Quality: Axolotls are sensitive to water quality. Regular water changes (20-30% weekly) are essential to maintain low levels of ammonia, nitrite, and nitrate.
- Substrate: Fine sand is the best substrate. Gravel or small rocks can be ingested, leading to impaction.
- Hiding Places: Provide plenty of hiding places, such as caves or plants, to reduce stress.
- Filtration: A good quality filter is essential, but the flow should be gentle, as axolotls don’t tolerate strong currents.
Comparing Axolotl and Fish Needs
| Feature | Axolotl | Typical Fish |
|---|---|---|
| —————- | ——————————————— | ——————————————— |
| Temperature | 60-68°F (16-20°C) | Often higher, 72-82°F (22-28°C) |
| Water Flow | Low, gentle | Variable, depends on species |
| Diet | Carnivorous, primarily worms and pellets | Highly variable, often flake-based |
| Tank Mates | Generally best kept alone or with other Axolotls | Variable, depends on species |
Common Mistakes When Keeping Axolotls
- Overfeeding: Overfeeding can lead to obesity and health problems.
- Incorrect Substrate: Gravel impaction is a serious risk.
- High Temperatures: Elevated temperatures are a major cause of stress and illness.
- Poor Water Quality: Neglecting water changes leads to toxic buildup.
- Incompatible Tank Mates: Attempting to keep axolotls with fish or other unsuitable species.
Alternative Tank Mates (Proceed with Caution)
While fish are generally not recommended, some hobbyists have had limited success with certain invertebrates, such as ghost shrimp or small snails. However, even these introductions carry risks. The shrimp may be eaten, and snails should be large enough to avoid ingestion. Close monitoring is always required. Remember that any introduction of a new creature to an axolotl tank comes with risk and should be researched thoroughly beforehand.
Frequently Asked Questions
Are there any fish that can safely live with axolotls?
It’s extremely difficult to guarantee the safety of any fish living with axolotls. While some larger fish might not be immediately eaten, the differing temperature and water quality needs make long-term cohabitation unadvisable. Also, axolotls are slow-moving and the quick fish might steal their food!
What happens if an axolotl eats a fish?
If an axolotl eats a small fish, it will likely digest it without issue. However, repeated ingestion of fish can lead to digestive problems, especially if the fish are bony or have hard scales. Larger fish can cause choking or impaction.
Can axolotls get sick from fish?
Yes, axolotls can contract parasites or diseases from fish. Fish can carry pathogens that are harmful to axolotls, even if the fish themselves appear healthy. This is another reason to avoid cohabitation.
Why do some people say they have successfully kept fish with their axolotls?
Every axolotl is different. Some may be more docile or less predatory than others. However, success stories are often short-lived or involve careful management of specific, non-aggressive fish species in a large, heavily planted tank. This doesn’t eliminate the inherent risks. These scenarios are the exception, not the rule.
What are the signs of stress in axolotls?
Signs of stress in axolotls include reduced appetite, lethargy, gill curling forward, and floating at the surface. If you observe these signs, immediately check water parameters and consider separating the axolotl from any potential stressors.
Do axolotls need tank mates?
Axolotls are generally solitary creatures and do not require tank mates. In fact, they often thrive best when kept alone. They don’t experience loneliness in the way humans do.
What if I already have fish in my tank and want to get an axolotl?
The best course of action is to set up a separate tank specifically for the axolotl. This ensures the axolotl receives the appropriate care and avoids any potential conflicts with existing fish.
Can axolotls live with snails?
Large snails, like mystery snails, can sometimes coexist with axolotls if the axolotl is well-fed. However, there’s always a risk the axolotl might try to eat the snail, or the snail may harass the axolotl. Observe closely!
Are ghost shrimp safe tankmates for axolotls?
Ghost shrimp are often considered hit or miss as axolotl tank mates. They might act as a clean-up crew, eating leftover food, or they might become a snack for the axolotl. It depends on the individual axolotl’s temperament.
What is the ideal tank size for one axolotl?
A 20-gallon long tank is generally considered the minimum size for one axolotl. A larger tank (30-40 gallons) is preferable, providing more space and helping to maintain stable water parameters.
How often should I feed my axolotl?
Juvenile axolotls should be fed daily, while adults can be fed every other day or every third day. Adjust the feeding frequency based on your axolotl’s condition.
What should I do if my axolotl gets injured?
Axolotls have remarkable regenerative abilities. Minor injuries often heal on their own in clean water. However, severe injuries require immediate veterinary attention. Consult an experienced aquatic veterinarian familiar with amphibians.
