Electric Blue Crossback

The Electric Blue Crossback Asian Arowana is a highly sought-after and beautiful variety of the Asian Arowana. Known for its vivid blue coloration and shimmering, metallic sheen, this variety has become a favorite among aquarium enthusiasts for its striking appearance and relatively rare occurrence in the wild. The Electric Blue Crossback is a type of crossback arowana, recognized for its distinctive coloration that appears to "glow" under the right lighting.

Scientific Name:

Scleropages formosus (Electric Blue Crossback Asian Arowana)

Maximum Size:

• The Electric Blue Crossback Asian Arowana can grow up to 24-36 inches (60-90 cm) in length, though the average size in captivity is typically around 24 inches.

• This species exhibits a more streamlined and sleek body compared to other varieties of arowanas, contributing to its elegant and powerful appearance.

Native Region:

• The Electric Blue Crossback Asian Arowana is native to Southeast Asia, particularly in countries like Malaysia, Thailand, and Indonesia.

• It inhabits slow-moving rivers, lakes, and swamps in regions with soft, acidic water and moderate to slow currents. The species is typically found in the middle to upper levels of the water column.

Diet (Carnivorous or Omnivorous?)

• Carnivorous, with a diet consisting mainly of small fish, insects, crustaceans, and other aquatic life.

• In captivity, Electric Blue Crossback Asian Arowanas are fed:
  ✅ Live foods such as small fish (feeder fish), crickets, shrimp, and worms.
  ✅ Frozen or freeze-dried foods like bloodworms, brine shrimp, and mysis shrimp.
  ✅ Pellets or granules made specifically for carnivorous species.
  ✅ Occasionally, they may accept vegetable matter such as spirulina.
  ❌ It's essential to avoid overfeeding and offering processed foods that are not high in protein, as this can lead to health issues.

Lifespan:

• Electric Blue Crossback Asian Arowanas can live for 15-20 years in optimal conditions, making them a long-term commitment for any aquarium keeper.

Breeding Season & Behavior:

• The Electric Blue Crossback Asian Arowana is an egg-laying species that practices mouthbrooding. The female lays her eggs, which are fertilized by the male. The male then incubates the fertilized eggs in his buccal cavity (mouth) until they hatch into small larvae.

• Both the male and female take turns protecting the eggs and ensuring that the hatchlings are kept safe until they can swim on their own.

• Breeding Season: The breeding of Electric Blue Crossback Arowanas can be triggered by the right environmental conditions such as temperature, food availability, and water quality. In the wild, this usually coincides with seasonal changes.

• The breeding process in captivity can be difficult to replicate due to the high requirements for water quality, space, and diet.

• Water temperature for breeding should be kept between 80-85°F (27-29°C), and the pH should be neutral to slightly acidic (6.5-7.5).

Best Tank Mates:

Electric Blue Crossback Asian Arowanas are territorial and solitary by nature, so it is essential to choose their tank mates carefully. They are generally best kept alone or with other peaceful, large fish that will not compete for space or food.

✅ Larger, peaceful species:

• Large cichlids, such as Oscars, Severums, and Red Devils (though these species must be carefully monitored for aggression).

• Large catfish, such as Plecos (Loricariids) or Synodontis catfish.

• Other large, peaceful species, including Arapaima, Pacu, and Red-Tailed Catfish.

• Other Arowanas, although keeping multiple Arowanas can sometimes result in aggression.

🚫 Avoid:

• Small species that may become prey, including tetras, guppies, and barbs.

• Aggressive fish or overly active species, such as African cichlids or fast-swimming fish, which may stress out the Arowana or provoke it.

• Schooling fish that might cause stress to the solitary nature of the Arowana.

Ideal Tank Conditions:

• Tank Size: A minimum of 180-250 gallons (680-950 liters) is recommended for a single Electric Blue Crossback Arowana, as they need a lot of space to swim and thrive.

• Water Temperature: The water should be kept between 80-85°F (27-29°C).

• pH: The water should be neutral to slightly acidic, with a pH between 6.5 and 7.5.

• Water Hardness: The water should be soft to moderately hard (around 5-15 dGH).

• Filtration: Excellent filtration is essential because these large fish produce a considerable amount of waste. Strong, reliable filtration systems are necessary to maintain water quality.

• Décor:

  • Provide open swimming space, as Electric Blue Crossback Arowanas are active swimmers.

  • Use driftwood and rocks, but avoid overcrowding the tank.

  • Live plants can be used but should be hardy, as the Arowanas may damage or uproot delicate plants.

  • A fine gravel or sand substrate is ideal.

• Water Movement: They prefer low to moderate water flow, so avoid strong currents that may stress them out.

⚠ Important Notes:

• Jumping behavior: Arowanas, especially the Electric Blue Crossback, are notorious jumpers. A secure tank lid is essential to prevent them from escaping the aquarium.

• Territorial nature: Electric Blue Crossback Arowanas can become territorial during breeding or if they feel threatened.

• Space requirements: Due to their large size and active swimming nature, Arowanas need ample space to thrive. A tank of at least 180 gallons is required for a single Arowana.

• Water quality: Like all Arowanas, the Electric Blue Crossback is highly sensitive to water quality. Regular water changes, proper filtration, and careful monitoring of water parameters are vital to keeping them healthy.

• Feeding: These fish are carnivorous and require a high-protein diet to remain healthy. They should be fed a variety of live or frozen foods to meet their nutritional needs.
