Rhad Ornatus Teewah Creek Rainbowfish Care Guide

Introduction

The Rhad Ornatus Teewah Creek Rainbowfish (*Rhadinocentrus ornatus*) is a stunning freshwater species celebrated for its vibrant colours and graceful swimming behaviour. Native to Australia, this species is a popular choice among aquarists for its beauty and engaging personality, making it an excellent addition to community tanks.

Natural Habitat

The Teewah Creek Rainbowfish is endemic to the freshwater streams and rivers of the Teewah Creek region in Queensland, Australia. They thrive in clear waters with plenty of vegetation, where they can find shelter and forage for food among aquatic plants and natural debris.

Aquarium Setup

A tank of at least 20 gallons is recommended for Rhad Ornatus Teewah Creek Rainbowfish, although larger tanks are preferable to provide ample swimming space. The aquarium should be well-planted with live or artificial plants, driftwood, and rocks to create hiding spots that mimic their natural habitat. A gentle filtration system is essential to maintain water quality.

Water Parameters

The ideal water temperature for Teewah Creek Rainbowfish ranges from 74°F to 82°F (23°C to 28°C), with a pH level between 6.5 and 7.5. They prefer slightly acidic to neutral water conditions. Regular water changes of about 20-30% per week are important to keep the water clean and stable for their health.

Diet and Feeding

Rhad Ornatus Teewah Creek Rainbowfish are omnivorous and require a varied diet. They can be fed high-quality flakes, pellets, and live or frozen foods such as brine shrimp, daphnia, and bloodworms. Including some plant-based foods, like spirulina flakes or blanched vegetables, will help ensure balanced nutrition. A varied diet supports their health and enhances their vibrant colours.

Behaviour and Social Structure

This species is known for its peaceful and social nature. Rhad Ornatus Teewah Creek Rainbowfish do best in groups of at least six or more, as this helps them feel secure and exhibit natural schooling behaviour. They are active swimmers and add dynamic movement to the aquarium, making them an engaging species to observe.

Compatibility with Other Species

Teewah Creek Rainbowfish are compatible with a variety of peaceful community fish. Suitable tank mates include tetras, rasboras, and other non-aggressive species. It is important to avoid housing them with aggressive or fin-nipping fish that could cause stress or harm to the rainbowfish.

Breeding

Breeding Rhad Ornatus Teewah Creek Rainbowfish in captivity is possible and can be achieved with the right conditions. They are egg scatterers and typically require a separate breeding tank with slightly warmer water (around 78°F or 26°C) and plenty of plants or spawning mops to encourage spawning behaviour. After spawning, the adults should be removed to prevent them from eating the eggs. The fry can be fed infusoria or finely crushed flakes once they hatch.

Health Considerations

Rhad Ornatus Teewah Creek Rainbowfish are generally hardy but can be susceptible to common freshwater fish diseases such as ich, fin rot, and fungal infections. Maintaining good water quality, providing a balanced diet, and monitoring for signs of illness are key to keeping them healthy. Regular tank maintenance and prompt treatment of any health issues will help ensure their well-being.

Conclusion

The Rhad Ornatus Teewah Creek Rainbowfish is a vibrant and lively addition to any community aquarium. With proper care, a well-maintained environment, and attention to their specific needs, they can thrive and provide endless enjoyment for aquarists of all levels.
