Introduction

Glossolepis dorityi, commonly known as Dority’s Rainbowfish, is a peaceful and visually stunning species native to the Grime River system in Australia and Papua New Guinea. Known for their unique zigzag stripes and vibrant coloration, these fish are a favorite among aquarists seeking an active and engaging species for the top levels of their aquariums.

Food and Feeding

Dority’s Rainbowfish are omnivorous and readily accept a variety of foods. Provide a high-quality flake food as the staple of their diet, supplemented with live or frozen treats such as brine shrimp, bloodworms, and daphnia. Offering these protein-rich foods 2-3 times a week will enhance their coloration and support overall health. Feeding small portions multiple times a day helps mimic their natural feeding habits.

Habitat and Tank Requirements

To recreate their natural habitat, set up a spacious tank with plenty of swimming areas and dense planting along the edges. Suitable plants include Java Fern (Microsorum pteropus), Vallisneria (Vallisneria spiralis), and Water Wisteria (Hygrophila difformis). Maintain water parameters within a pH range of 6.5-7.8, hardness of 12-16°N (214.29-285.71 ppm), and a temperature of 24-27°C (75.2-80.6°F). A moderate current and high water quality are essential for their well-being. Use a dark substrate to accentuate their vibrant colors.

Sexing

Males are more colorful and exhibit a series of distinctive zigzag stripes along their bodies. The bottom half of their body is more vibrant than the top, and they possess extended rays on their first dorsal fins. Females, on the other hand, are silver and lack the zigzag pattern, making them easier to distinguish.

Breeding

Breeding Glossolepis dorityi is relatively straightforward. Set up a breeding tank with a spawning mop or fine-leaved plants to encourage egg-laying. Reduce the water current to create a calm environment. Eggs are laid over several months, so regularly check the spawning mop and move it to a separate tank for hatching. The fry are extremely small and require Infusoria as their first food. Gradually transition them to larger foods, such as baby brine shrimp, as they grow.

Lifespan

With proper care, the expected lifespan of Dority’s Rainbowfish is approximately 7 years, making them a long-term commitment for dedicated aquarists.

Behavior and Compatibility

Dority’s Rainbowfish are peaceful and highly social, thriving in groups of six or more. They are ideal for community tanks with other peaceful species such as Neon Tetras (Paracheirodon innesi), Harlequin Rasboras (Trigonostigma heteromorpha), and Dwarf Gouramis (Colisa lalia). Avoid housing them with aggressive or much larger tank mates, as this can cause stress. Their active nature and schooling behavior make them a lively addition to the top levels of any aquarium.

Short Description

Glossolepis dorityi, or Dority’s Rainbowfish, is a stunning species renowned for its vibrant markings and peaceful temperament. Best suited for well-maintained, planted aquariums, they thrive in groups and bring dynamic activity to the top levels of a tank. Their unique patterns and ease of breeding make them a rewarding species for both novice and experienced aquarists.
