Acclimate them to the water conditions of the axolotl tank by placing them in a separate container. This process allows the tank mates to adapt before being released into the main tank, reducing stress for the axolotls and the new companions.
Feeding Considerations: Juvenile axolotls have hearty appetites and may consume smaller tank mates if they fit into their mouths. Providing a balanced diet for all inhabitants, including live food like brine shrimp, is essential to minimize predatory behavior and ensure the entire community’s well-being.
Habitat and Space: Tank mates that prefer the bottom of the tank or are fast swimmers can coexist effectively with juvenile axolotls. Consider adding bottom-dwelling fish like cory catfish, which create a diverse and engaging environment. Peaceful creatures that inhabit different tank levels are also a good idea.
Species Research: Thoroughly researching potential tank mates’ behavior and specific needs is critical. For example, freshwater fish like guppies or tropical fish, freshwater shrimp-like glass shrimp or amano shrimp, and cold water snails like bladder or ramshorn snails could be suitable companions for juvenile axolotls.
Observation and Monitoring: Regularly observing the interactions between juvenile axolotls and their tank mates is key to ensuring their compatibility. Watch for signs of aggression, territorial behavior, or bacterial infections. If any issues arise, consider separating the individuals and reevaluating the selection of tank mates.
In general, if you have a juvenile Axolotl, it will most be able to live harmoniously with many fishes, including the 12 listed later. Even so, as fish keepers, we need to observe to ensure the safety of Axolotls and the inhabitants with it.
