The Rosy Barb (Pethia conchonius), also known as the Red Barb, is a colorful freshwater fish native to the rivers and streams of India, Bangladesh, and Nepal. They belong to the family Cyprinidae and are known for their striking coloration, with males displaying vibrant red and orange hues.
Rosy Barbs are popular in the aquarium hobby due to their active nature, attractive appearance, and ease of care.
These fish are known to be peaceful and can coexist with a variety of tankmates, making them suitable for community aquariums. They are shoaling fish, meaning they thrive when kept in groups of five or more individuals.
In their natural habitat, Rosy Barbs inhabit slow-moving waters with abundant vegetation.
Water Size
One individual Rosy Barb typically requires a minimum tank size of 20 gallons (approximately 76 liters) due to their active nature and the need to keep them in groups.Recommended Water Parameters
Temperature: 68-77°F (20-25°C)pH: 6.5-7.5
Water Hardness: 5-15 dGH
Ammonia, Nitrites, and Nitrates should be kept at minimal levels through regular water changes and maintenance.
Water Changes
Regular water changes of 20-25% every 1-2 weeks help maintain water quality and promote the health of Rosy Barbs.Schooling Behavior
Rosy Barbs are shoaling fish and thrive when kept in groups of five or more individuals. They exhibit more natural behavior and are less stressed in the company of their own kind.Air Pump
While not necessary, an air pump can enhance oxygen exchange and water circulation, especially in tanks with limited surface agitation.Filter
A filter is preferred and recommended to maintain water quality by removing waste and toxins.Tank Cover
A tank cover is not strictly necessary, but it can prevent fish from jumping out and provide added security.Aquarium Lighting
While not necessary, aquarium lighting can enhance the colors of Rosy Barbs and promote plant growth if live plants are present in the tank.Heater
A heater may be required to maintain a stable water temperature within the recommended range, especially in cooler environments.Substrate
They are flexible regarding substrate and can thrive with various types, including sand, fine gravel, or planted substrates.Interaction with Plants
Rosy Barbs typically interact well with live or artificial plants in the aquarium. Plants provide shelter and a natural environment.Feeding Regimen
They are omnivorous and should be fed a balanced diet consisting of high-quality flakes or pellets designed for tropical fish. Supplement their diet with occasional live or frozen foods like brine shrimp or daphnia. Feed them 2-3 times a day, only what they can consume in a few minutes.Lifespan
Rosy Barbs have an average lifespan of 5-7 years, although with proper care, some individuals can live longer.Interesting Facts
