Parkinsoni rainbowfish

Introduction

The Parkinsoni rainbowfish (Melanotaenia parkinsoni), also known as Parkinson's rainbowfish, is a vibrant freshwater species cherished by aquarists for its striking coloration and active demeanor. Native to Papua New Guinea, these fish display a captivating blend of silvery-blue bodies adorned with bright orange fins and markings, especially prominent in males. Their relatively straightforward care requirements make them suitable for both beginner and intermediate fishkeepers seeking to add dynamic beauty to their aquariums.

Care and Environment

Providing optimal care for Parkinsoni rainbowfish involves replicating their natural habitat conditions to ensure their health and vibrancy.

What is the minimum tank size required for Parkinsoni rainbowfish?

A minimum tank size of 100 liters is recommended to accommodate a small group of these active swimmers.

What are the ideal water parameters for Parkinsoni rainbowfish?

Maintain water temperatures between 24°C and 28°C, with a pH range of 6.5 to 7.5, and water hardness between 8 to 12 dGH.

How should the tank be set up for Parkinsoni rainbowfish?

Incorporate ample swimming space with areas of dense vegetation, using plants like Java Fern and Anubias, to mimic their natural environment.

Effective filtration is crucial to maintain water quality, as these fish are sensitive to pollutants. A filter providing gentle to moderate flow is ideal. Regular water changes, approximately 10-20% weekly, help keep nitrate levels low and water conditions stable.

Parkinsoni rainbowfish are omnivorous and thrive on a varied diet. High-quality flake or pellet foods should form the staple of their diet, supplemented with live or frozen foods like bloodworms, brine shrimp, and daphnia to enhance coloration and health.

When setting up the tank, use a dark, fine-grained substrate to accentuate their colors. Include rocks, driftwood, and caves to provide hiding spots, but ensure there is ample open space for swimming.

Origin and Habitat

Parkinsoni rainbowfish are endemic to the southeastern regions of Papua New Guinea, specifically between the Kemp Welsh River and Milne Bay. They inhabit lowland rainforest streams and pools, environments characterized by warm, clear waters with moderate flow. These habitats are often surrounded by dense vegetation, providing both shelter and feeding grounds. The natural conditions include temperatures ranging from 26°C to 30°C, with slightly alkaline pH levels between 7.5 and 7.8.

Temperament and Compatibility

Parkinsoni rainbowfish are peaceful, schooling fish that thrive in groups of six or more. Keeping them in such numbers reduces stress and encourages natural behaviors, including vibrant displays by males vying for attention.

What tank mates are suitable for Parkinsoni rainbowfish?

They are compatible with other peaceful community fish such as tetras, rasboras, peaceful barbs, and small catfish species.

Are there any fish species to avoid housing with Parkinsoni rainbowfish?

Avoid keeping them with aggressive or fin-nipping species that may intimidate or harass them.

Providing a well-planted tank with open swimming areas allows them to exhibit their natural schooling behavior and reduces potential stress.
