Scientific Name: Osteoglossum bicirrhosum (Albino variant)
Common Names: Albino Silver Arowana, Albino Arowana
Origin: Amazon Basin (South America), in slow-moving waters like flooded forests, lakes, and river basins
Rarity: Albino version is very rare and highly valued in the aquarium trade
Color: White to pearly-gold body with red or pink eyes (due to albinism)
Shape: Long, streamlined body with large metallic scales
Barbels: Two long sensory barbels extending from the lower jaw
Fins: Long dorsal and anal fins that nearly meet the tail, giving a flowing, ribbon-like appearance
Juveniles: May show light yellow or blue tints that fade with age
Adult Size: Up to 3 feet (90 cm) in captivity
Lifespan: 10–15 years typically, over 20 years with excellent care
Growth Rate: Fast-growing when properly fed and housed
Minimum Tank Size: 250 gallons for a single adult
Ideal Setup: Wide and long tank with a tight-fitting lid (they are strong jumpers)
Water Parameters:
Temperature: 75–82°F (24–28°C)
pH: 6.5–7.5
Hardness: 1–15 dGH
Ammonia/Nitrite: 0
Nitrate: <30 ppm
Filtration: Powerful filtration system with high oxygenation
Substrate & Decor: Bare bottom or soft substrate; minimal decorations to avoid injury
Lighting: Moderate; avoid harsh lighting to reduce stress
Type: Carnivore
Preferred Foods:
Floating carnivore pellets
Frozen/thawed shrimp, krill, silversides
Insects (crickets, mealworms)
Occasional live foods (feeders only if quarantined)
Feeding Frequency:
Juveniles: 2–3 times daily
Adults: Once daily
Tips: Avoid overfeeding; promote surface feeding to prevent "droopy eye" syndrome
Temperament: Semi-aggressive, solitary as adults
Behavior: Surface-dwelling predator, calm when unprovoked
Compatibility:
Suitable Tankmates: Large, peaceful or semi-aggressive species (Oscar fish, Bichirs, Silver Dollars, Datnoids, large Plecos)
Avoid: Small fish (may be eaten), aggressive tankmates, or fin-nippers
Note: Best kept alone or with similarly sized, non-aggressive species in a massive tank
Type: Egg-layer; male is a mouthbrooder
Spawning: Rarely occurs in home aquariums due to size and environmental requirements
Parental Care: Male carries fertilized eggs and fry in his mouth for 6–8 weeks
Difficulty: Extremely difficult to breed in captivity—usually done in specialized farms
Jumping Risk: Very strong jumpers—always use secure lids
Sensitive to Water Quality: Pristine water conditions required
Droopy Eye Risk: Can occur from bottom feeding or poor water quality
Light Sensitivity: Due to lack of pigmentation, they may prefer subdued lighting
