Dwarf Arowana Fish In A Tank: Care Secrets Revealed

Caring for a Dwarf Arowana fish in a tank can be a challenging but rewarding experience. To ensure your pet’s health and well-being, it is important to understand the specific needs of these gorgeous fish.

Taking care of dwarf Arowana fish in a tank requires specific knowledge and attention to detail. These beautiful and delicate creatures require a carefully curated environment to thrive. Here are some care secrets revealed for keeping dwarf Arowana fish in a tank:

1. Tank Size

Dwarf Arowana requires a spacious tank to accommodate their specific needs. The recommended tank size for these fish is at least 20 gallons, with 30 gallons being ideal.

It’s important to note that the water depth should be between 12-16 inches as these fish are excellent jumpers and can easily escape an insufficiently sized tank. To make the most of this habitat, provide plenty of rocks and hiding spots for your fish to explore.

2. Water Parameters

Water Parameters

Water Parameters: It’s essential to maintain the correct water parameters for optimal health. The ideal pH level for Dwarf Arowana should be between 6.5-and 7.5, with a water temperature range of 75-80 degrees Fahrenheit.

Additionally, the water hardness should range from 5-15 dH. To ensure that your fish stay healthy, use a high-quality water testing kit to monitor the parameters of your tank regularly.

3. Tank Setup

It is easier to set up a tank with dwarf varieties, but it still needs proper lighting conditions. For the minimum oxygenated water volume necessary, recommend two 5-gallon community aquariums for each sex since they don’t grow too large aquariums and may not make more than one male otherwise.

Also, provide both larger tanks that are at least 16 inches tall, as that will allow them enough room to move around where your particular taste and favorite sites are located in either of those choices.

The average height for an aquarium is about 30″. So it’s acceptable to have the females higher up while males are slightly longer. You will also want plenty of hiding places and two different versions you can alternate either by having one end nude while getting started with other species.

4. Temperature And Lighting

Temperature And Lighting

The temperature in the tank should range between 76-86 degrees Fahrenheit. It is absolutely necessary that you provide your Dwarf Arowana with a very strong light source, preferably LED or metal halide lighting, as they require a bright environment to thrive. Provide adequate shade for your fish by adding floating plants and rocks that will block out some of the direct light.

5. Feeding & Diet

Dwarf Arowana fish have a hearty appetite and should be fed two to three times daily. Offer a variety of food types, such as bloodworms, tubifex worms, brine shrimp, and other frozen or freeze-dried foods. Live foods such as insects are also acceptable. Feed small portions at a time to avoid overfeeding.

At first, start each morning, feeding about halfway up to get them overeating since they seem to do best when the feedings thin down. You will then gradually increase that up to 2 – 3 times a day over the next few days until you feel it appropriate.

At any point, if at all possible, try using real plant material as a mix in foods by simply shredding the leaves and stems into nice-sized pieces, which they can easily sink through their mouths with ease.

6. Arowana Tank Mates

Arowana Tank Mates

Regarding keeping Dwarf Arowana fish tank, choosing the right tank mates is crucial for their well-being. One popular option for tank mates is cichlid pellets. These pellets are specifically formulated to meet the nutritional needs of cichlids, which can be compatible with Dwarf Arowanas.

Cichlid pellets provide a balanced diet and help ensure that all the fish in the tank get the nutrients they need to thrive. However, monitoring the feeding process closely is important to avoid overfeeding and maintain water quality. Additionally, it is always recommended to do thorough research and consult with experts or experienced aquarists before introducing any new fish or food into your aquarium.

7. Breeding

Breeding Arowana fish is not particularly difficult, but it takes some careful preparation and dedication to ensure success. When the time is right for breeding, the male will build a bubble nest near the surface of the water current. The female should be added to the tank shortly afterward, as she will lay her eggs in the male’s nest.

It is important to provide plenty of hiding spots throughout the tank for the female so she can retreat after spawning. The male will take care of the eggs, and once they hatch. He will continue to watch over the fry until they are big enough to fend for themselves.

How Dwarf Arowana Fish Hatch?

Dwarf arowanas mature after they are around six years old and migrate upstream. When it’s time to breed their eggs, they typically lay up to 400 eggs in May through June at spawning sites along with pairing with female dwarf arowana or Thai pot-bellied grey fish (Hucho) and spawning in June through July.

The fish can reach sexual maturity at about two years old after they reach 1 foot long and 10 inches square. The female only lays eggs once a year during their adult life. So, keeping these species as pets for up to 3-5 years before breeding them is normal.
