Axolotls are a unique species of aquatic creatures that have captivated the attention of biologists and aquarium enthusiasts alike. Their fascinating appearance, intricate behavior, and ability to regenerate lost body parts make them a highly sought after pet in many areas around the world.
But what types of fish can you mix with axolotls? In this article, we will discuss which fish are best suited for living with an axolotl as well as provide tips on creating a healthy environment where both species may thrive.
Axolotls can share a tank with certain fish species, although there is the risk to smaller fish of being eaten, and a risk to the axolotl of becoming stressed and nipped.
In order to create a successful home aquarium, it is important to understand the biology and needs of all inhabitants before introducing them into the same space. This includes determining compatibility between different species so they can coexist without any negative effects on their health or wellbeing.
By understanding these factors, one is able to create a suitable environment for both fish and axolotls to live together.
Compatibility Between Fish And Axolotls
When considering the compatibility of fish and axolotls in an aquarium, there are several factors to look at.
From a biological standpoint, it is important to note that axolotls are carnivorous animals who feed on worms, larvae, insects, small fish, and crustaceans. As such, putting fish in with them runs the risk of the fish becoming a meal if they aren’t big enough.
Some species of fish can be quite aggressive towards one another and this could lead to stress for the axolotl, especially if there are a number of fish in the tank. Therefore, when selecting compatible tank mates for an axolotl it is best to choose non-predatory species that are relatively peaceful in nature such as Danio rerio (Zebrafish) and Rasbora heteromorpha (Harlequin rasboras).
It’s important to not choose fish that have any spines or features that could damage the delicate exterior of your axolotl. Also be aware that some fish might want to nip.
It is also important to ensure that any chosen companion requires similar water parameters.
Factors To Consider When Mixing Fish And Axolotls
When considering mixing fish and axolotls in an aquarium, water parameters are a critical factor. Water temperature, pH, and hardness levels must be carefully monitored and adjusted as necessary to ensure the health of both species.
Importantly, the tank must be large enough to support both species with adequate room for swimming and hiding spots.
Water Parameters
When considering which fish to mix with axolotls, it is important to evaluate the water parameters of the tank.
The ideal pH range should be between 6 and 8, while temperature should not exceed 72 degrees Fahrenheit.
Ammonia levels must remain at 0ppm, nitrite levels at 0-0.5ppm and nitrate levels below 20 ppm.
Additionally, a softening agent like peat moss or aquarium salt can be added in order to help maintain the correct hardness level for both species.
With these conditions met, both axolotl and fish will have the best home possible.
Tank Size
When it comes to mixing fish and axolotls, tank size is an essential factor that must be taken into account.
The ideal tank size for a combination of both species should allow enough room for each inhabitant to move freely without feeling cramped or crowded. For a single axolotl the recommended tank size is around 15-20 gallons. This should be increased by at least 10 gallons for the introduction of fish.
A larger tank is better equipped to maintain stable water conditions over time, due to their greater volume. This is because the axolotl can produce a lot of waste.
The pefect tank will be wider than it is tall to give the axolotl plenty of room to roam around in.
Best Fish Species For Axolotl Aquariums
When selecting the right fish to house alongside axolotls, it is important to ensure that they are compatible in terms of water parameters and dietary needs. Furthermore, a robust filtration system should be implemented as part of an effective tank maintenance routine.
In addition, certain species may exhibit aggression towards one another or even the axolotl itself, so careful consideration must be taken when deciding which fish to include in the aquarium. Tankmates should also not out-compete the axolotl for food and resources; thus, small schooling fish with peaceful temperaments such as Danio rerio (Zebrafish) and Rasbora heteromorpha (Harlequin rasboras) are often ideal choices for housing alongside these amphibians.
Caring For Fish And Axolotls Together
Caring for fish and axolotls together is possible, but there are certain considerations to take into account.
Firstly, it’s important that the environment of the tank is suitable for both species. Axolotls need a freshwater aquarium with slow-moving water, whereas fish require a filtration system to maintain cleanliness in the water.
Secondly, different types of fish can be kept alongside an axolotl, provided they are not too large or territorial:
-
Danios
-
White Clouds
-
Guppies
-
Rummy Nose Tetras
Thirdly, when housing them together it’s essential to ensure that the majority of food sources such as worms and insects reach the bottom of the tank so that the axolotl can feed without competition from other inhabitants.
Finally, as previously mentioned it’s also important to keep in mind that some fish may become snacks for your pet axolotl, if they’re smaller than their mouth!
With these points taken into consideration you should have no problem successfully keeping fish and axolotls in one tank.
Frequently Asked Questions
What Is The Optimal Water Temperature For Axolotls?
Aquatic biologists have studied the optimal water temperature for axolotls and found that a range of 15-20 degrees Celsius is ideal.
This temperature encourages their natural behavior, such as feeding, mating, and reproduction.
Furthermore, this level allows them to stay healthy in captivity while providing ample oxygenation.
To maintain these temperatures, it is best to use an aquarium heater with a thermostat or some other reliable method of controlling the environment.
It should also be noted that fluctuations in temperature can cause stress on the animal and potentially lead to illness or death.
What Type Of Filtration System Should I Use For A Tank Containing Both Axolotls And Fish?
When housing axolotls and fish in the same tank, it is essential to properly filter the water. A filtration system should be chosen based on a few key factors including the size of the tank, number of inhabitants, and type of fish kept.
Canister filters are recommended for tanks containing both axolotls and fish due to their large capacity for water flow through mechanical, chemical and biological media.
This allows them to provide effective removal of solid waste particles from the aquarium environment as well as providing an ideal habitat for beneficial bacteria that help maintain healthy levels of ammonia and nitrates.
What Is The Best Way To Feed Both Axolotls And Fish?
When feeding axolotls and fish together, it is important to consider the nutritional needs of both species.
Axolotls are carnivorous, so they should be fed live or frozen foods such as worms, brine shrimp, and bloodworms.
Fish can usually feed on flake food or pellet food along with occasional treats like freeze-dried krill.
When providing a balanced diet for both species, it’s also important to remember not to overfeed either one.
Overfeeding can cause water quality problems in an aquarium containing both axolotls and fish.
How Many Fish Can I Safely Add To A Tank With An Axolotl?
When it comes to adding fish to a tank with an axolotl, the exact number depends on the size of the tank and the types of fish being added. Generally speaking, however, caution should be taken when adding too many fish as they may compete for food or become aggressive toward the axolotl.
It is recommended that no more than four small-sized schooling fish such as tetras be added to any one aquarium containing an axolotl in order to ensure their safety.
Conclusion
When keeping Axolotls and fish together in an aquarium, important considerations must be taken into account. It is essential to maintain optimal water temperature, remove waste regularly and use a suitable filtration system.
Furthermore, both species should be fed correctly and the tank size should permit enough space for all inhabitants. With proper care, it is possible to keep various types of compatible fish with Axolotls without risking their health or wellbeing.
An experienced aquarist can ensure that conditions are favourable for all aquatic life within the tank by following the guidelines outlined above.
