Killifish and guppies are two of the most popular aquarium fish that many fish enthusiasts would love to keep in their tanks. However, the question of whether these two species can coexist in the same tank has been a subject of debate among fish keepers.
In general, killifish and guppies can live together peacefully if certain conditions are met. First, it is important to note that killifish are predators and may eat smaller fish like guppies. Therefore, it is advisable to keep killifish with larger guppies that can hold their own against the predators.
Secondly, it is crucial to ensure that the aquarium is spacious enough to accommodate both species. Killifish are known to be territorial and may become aggressive towards other fish if they feel cramped. Therefore, a tank with a minimum of 20 gallons is recommended for a small group of killifish and guppies.
Another important factor to consider is the water parameters. Killifish prefer slightly acidic water with a pH range of 6.0-7.0, while guppies thrive in slightly alkaline water with a pH range of 7.0-8.0. Therefore, it is essential to maintain a neutral pH level of around 7.0 to ensure the well-being of both species.
Lastly, it is essential to provide adequate hiding places for both species. Killifish and guppies both appreciate having hiding spots in the aquarium. This not only provides a sense of security but also helps to reduce stress levels in the fish.
In conclusion, killifish and guppies can live together in the same tank as long as certain conditions are met. With proper care and attention, these two species can coexist peacefully and provide a beautiful display in any aquarium.
