Silver Arowana (7-8 Inches)

The Silver Arowana (Osteoglossum bicirrhosum) is a striking freshwater fish known for its impressive size, elegant swimming style, and metallic sheen. Here’s what you need to know about this popular aquarium species:

Description:

Appearance: Silver Arowanas have a long, streamlined body covered with reflective silver scales that shimmer beautifully in the light. They feature long pectoral and dorsal fins, giving them a graceful look.

Size: At 7-8 inches, these juvenile arowanas are still growing and can reach lengths of up to 3 feet in captivity, so they require adequate space as they mature.

Habitat:

Natural Environment: Found in the slow-moving waters of the Amazon River Basin, they prefer warm, freshwater habitats with plenty of vegetation and cover.

Care in Aquariums:

Tank Size: A minimum tank size of 120 gallons is recommended for adult Arowanas, so plan for their growth when setting up your aquarium.

Water Conditions: They thrive in slightly acidic to neutral water (pH 6.0-7.5) and prefer temperatures between 75°F and 82°F (24°C to 28°C). Good filtration and water quality are essential.

Diet: Silver Arowanas are carnivorous. At this size, they can be fed high-quality pellets, live foods like minnows, and frozen options like shrimp or bloodworms.

Behavior:

Temperament: Generally peaceful but can be territorial, especially as they grow. It’s best to keep them with larger, non-aggressive fish to avoid bullying or stress.

Swimming Style: They are active swimmers and appreciate plenty of open swimming space.
