Why Add Boesemani Rainbows to Your Aquarium?

Boesemani Rainbows are among the most sought-after freshwater species for aquarists across Canada due to their hardiness and vibrant aesthetics. Explore our full collection of live exotic livestock to build your ultimate tank display.

Unmatched Coloration & Active Schooling

While juvenile specimens appear mostly silver, mature Boesemani Rainbowfish develop rich jewel tones as they settle into established aquariums. Keeping them in schools of 6 or more encourages active shoaling and prompts males to display fiery orange hues during morning courtship displays.

Excellent Community Tankmates

Reaching an adult size of 3.5 to 4.5 inches, Boesemani Rainbowfish are non-aggressive, mid-to-top-water swimmers. They thrive alongside peaceful tankmates, including tetras, rasboras, peaceful cichlids, gouramis, and bottom-dwelling catfish.

Care Guide & Optimal Tank Parameters

To maintain their vibrant coloration and longevity, provide clean, well-oxygenated water with moderate current. You can equip your setup using our premium canister filters and water treatments.

Tank Setup & Water Quality

• Minimum Tank Size: 40 Gallons (55+ gallons recommended for full schools)

• Temperature: 75°F – 82°F (24°C – 28°C)

• pH Range: 7.0 – 8.0 (Hard, slightly alkaline water preferred)

• Aquarium Environment: Provide open swimming space in the center, flanked by dense background live plants, driftwood, and high-quality filtration.

Diet & Feeding Requirements

Boesemani Rainbows have narrow throats, so smaller food items are ideal. Feed a diverse diet of high-protein, color-enhancing micro-pellets, high-grade flakes, and frozen foods like bloodworms, brine shrimp, and daphnia available in our aquarium food catalog.

Frequently Asked Questions (FAQs)

How large do Boesemani Rainbowfish grow?

Adult Boesemani Rainbowfish typically reach 3.5 to 4.5 inches in length, with males growing slightly larger and displaying significantly deeper blue and orange contrast than females.

How many Boesemani Rainbows should be kept together?

They are a schooling species and should be kept in groups of at least 6 to 8 individuals. Maintaining a ratio with more females than males reduces male competition and stimulates vibrant color displays.

Young or stressed fish naturally lose their color during shipping and transition. Once acclimatized to stable water parameters and fed a nutrient-dense diet, their signature neon-blue and yellow-orange tones will fully develop.
