Hyphessobrycon Notidanos "Red"

Introducing the Hyphessobrycon notidanos "Red" — a captivating Amazonian jewel that brings a bold, multicolored presence to any freshwater setup. Native to the upper drainage of Brazil’s Rio Tapajós and scientifically described in 2006, this small tropical fish has distinct color morphs that hobbyists prize for their dramatic contrast. The "Red" variant showcases a vivid red body paired with a striking blue iris, creating a dynamic centerpiece in a thoughtfully planted or open tank.

What makes this Red morph truly stand out

• Eye-catching color dynamics: a rich red body that glows under proper lighting, offset by a cool blue iris for a look that’s both electric and elegant.
• Distinctive morph within a single species: alongside the related "Yellow Devil" iris variation, the Red showcases a unique color profile that adds depth and variety to any shoal.
• Active, graceful schooling behavior: small, peaceful tetra that swims in cohesive groups, delivering movement and color in synchronized, eye-level displays.

Ideal tank setup and parameters

This species thrives in a well-maintained, peaceful community tank with stable water conditions. Create an environment that mirrors its natural Amazonian roots while highlighting its color:

• Tank mates: pair with other small, non-aggressive tetras, rasboras, dwarf gouramis, and similar peaceful species.
• Lighting and plants: moderate to slightly bright lighting helps bring out the red hue and blue iris; consider a mix of open swimming space and leafy cover to reduce stress.
• Schooling: these fish shine when kept in a group (6–8 or more). A active school increases color intensity and natural behavior.
• Diet: omnivorous and adaptable — offer a varied menu of high-quality flakes or pellets, supplemented with small live or frozen foods to encourage color development and vitality.
• Size and space: expect a compact adult size; provide ample horizontal space for schooling and swimming in a aquarium of reasonable size to keep the group cohesive.

Care and longevity — what to expect

The Hyphessobrycon notidanos "Red" is approachable for hobbyists who want a striking, low-to-moderate maintenance fish in a community tank. Key care points to maximize color and health:

• Water quality: maintain clean, stable water with regular partials changes. The Red morph responds well to consistent conditions.
• Color optimization: reliable results come from steady conditions and a varied diet rather than dramatic changes in routine.
• Breeding notes: while many tetras breed under ideal conditions, this species may require specialized setup and careful conditioning; it’s best approached by experienced hobbyists who enjoy observing natural spawning behavior.

Who will love the Hyphessobrycon notidanos "Red"

• Aquarists seeking a distinctive, color-packed centerpiece with dynamic schooling behavior.
• Collectors looking to expand a Brazilian/Amazonian-themed community tank with a true color morph that stands apart from standard tetra varieties.
• Owners who enjoy observing how lighting and environment enhance color, particularly the red body and blue iris contrast in this morph.

With its dramatic Red morph and blue iris, the Hyphessobrycon notidanos "Red" offers a unique, living show in a well-planned aquarium. It’s not just another fish — it’s a vivid reminder of Brazil’s rich aquatic biodiversity, ready to brighten your freshwater setup with personality, color, and natural allure.
