Arowanas are one of the most sought-after freshwater aquarium fish due to their beautiful appearance and considerable size. One of the most fascinating aspects of keeping arowanas is attempting to breed them. Successfully breeding arowanas requires meticulous planning and preparation, starting from creating a suitable breeding environment. In this article, we will discuss the essential steps for setting up a breeding tank for arowanas.

The first step in creating a spawning tank for arowanas is choosing the right supplies. The tank should be a minimum of 2.5 feet long, 1.5 feet wide and 2.5 feet tall. This size of tank provides sufficient space for the breeding arowanas and allows sufficient room for a water current. A glass tank is ideal as metal tanks are prone to rust when directly exposed to substances. A cover is also essential to prevent the arowanas from jumping out of the tank, especially during breeding.

The next step is setting up the filtration system. Arowanas are very sensitive to water quality, so a reliable filtration system is crucial.

You can choose a internal filter or a wet-dry filter, but make sure it is capable of producing both mixed water currents. A weak current is necessary to help the arowanas conserve energy while breeding, while a strong current will simulate natural ocean currents and help the eggs incubate properly. It's also essential to add a chemical device as arowanas are sensitive to high levels of ammonia.

Temperature is another critical factor to consider in a breeding tank for arowanas. Arowanas prefer a slightly acidic water with a pH of between 6.0 and 7.5. You can adjust the pH level of the water by using pH adjustments or peat moss as a natural filter media. The ideal temperature for breeding arowanas varies depending on the species, but most thrive between 80-88°F (26-31°C).

Lighting is also an important consideration in the breeding tank. Arowanas prefer diffused lighting, so it's recommended to use energy-efficient aquarium lighting. A photoperiod of 10-12 hours of light and 12-14 hours of darkness will mimic the natural day-night cycle. This photoperiod helps regulate the arowanas' internal clock and improves their overall health.

Once the tank has been set up, the next step is acclimating the arowanas to the breeding tank. It's essential to introduce the arowanas slowly, allowing them to adjust to the tank's temperature, pH, and water flow. Begin by placing the arowanas in a separate holding tank before transferring them to the breeding tank.

The female arowana will typically dig a shallow nesting area using sand once she is ready to spawn. The male will also defend the territory from other arowanas. You can introduce a few large substrate or hoses to create an underwater cave for the arowanas to hide and breed.

After the spawning is complete, the female Red Arowana for sale will deposit the eggs in the nesting area. The eggs will then incubate for 8-12 hours, depending on the species, before hatching. Arowana fry are very sensitive to high water currents and predators, so it's essential to maintain a stable, quiet environment in the breeding tank. Once the fry have hatched, you can begin feeding them commercial arowana food flakes and live or frozen foods.

Breeding arowanas requires dedication and precise breeding conditions. With proper equipment, a well-planned tank setup, and proper acclimation of the arowanas, you may be able to successfully breed these majestic fish.
