Also, danios are fast, active swimmers, and being surrounded by all that movement can be stressful for your betta fish.Ī stressed betta will quickly develop health problems, and damaged fins are likely to become infected by bacteria. While bettas are an aggressive and territorial fish species, danios are active fish that can be nippy and will hassle your poor betta, attracted by his long, flowing fins. Zebra danios also like to swim in the mid to upper reaches of the water column, which brings them into direct confrontation with the betta fish.īettas are highly territorial and can be very aggressive if confronted by a perceived rival on their patch. Betta fish are labyrinth breathers, and they need to periodically breathe atmospheric air via their labyrinth organ at the water surface. That’s because bettas are surface feeders, hunting for water-bound insects and even leaping out of the water to grab flies as they hover over the water.
Behaviorīettas and danios are not a good fit when it comes to their behaviors.īetta fish mostly like to hang out in the upper area of the water column, close to the surface. Use an aquarium water testing kit to run water tests every week. Ideally, you should carry out partial weekly water changes of up to 20% fresh water and have a high-quality filtration system installed in your fish tank. Tank Maintenanceīettas are surprisingly sensitive to water quality, so you’ll need to carry out frequent water changes and monitor the water parameters regularly. That said, captive-bred danios are often raised in warm water and sold as a tropical species, so they can tolerate temperatures at the cooler end of the betta’s range. However, danios prefer cooler conditions of 64° to 77° F. Bettas are tropical fish that need warm water temperatures of 78° to 82° F. However, these two ornamental fish species have slightly different water temperature preferences. Water Parametersīetta fish and Zebra danios share similar water parameter needs, such as a pH between 6.0 and 8.0, and water hardness in the range of 5 to 20 dH. That can help to prevent aggression and make the fish feel more settled and secure. So, you need lots of natural planting in your tank, as well as some resting spots for your betta, pieces of driftwood, twisted roots, and rockwork to create natural barriers and areas that the fish can establish as territories. In captivity, like bettas, danios like a well-planted habitat, and they prefer a slow flow rate, but they also need plenty of open swimming space. Zebra danios share similar wild habitats. The water here is stagnant or very slow-moving. In the wild environment, betta fish live in heavily vegetated habitats, including ponds, shallow bodies of water, rice paddies, and slow-moving streams. Danios are also schooling fish that need to be kept in large groups, so a larger tank of at least 20 gallons is essential to prevent overcrowding and fighting.
However, bettas are temperamental fish that can be very aggressive, and keeping them in a small tank with speedy swimmers is asking for trouble. That makes both these species very popular for inclusion in home fish tanks. Tank Sizeīetta fish and Zebra danios (Danio rerio) are classed as nano fish because they can live in smaller aquariums. Tank Conditionsįirst of all, let’s see whether Bettas and danios can tolerate the same tank conditions. So, let’s take a closer look at whether these two species could ever live in harmony. However, danios do better when kept in cooler conditions of 64° to 77° F.Īlso, bettas are temperamental fish that can be aggressive, especially around feeding times, which can be highly problematic when these two species collide.

Can Your Betta Live With Zebra Danios?Īs you will discover, Zebra danios aren’t the most suitable companions for betta fish for several reasons.īettas are tropical fish that need warm water temperatures of between 78° and 82° F to thrive.
