Long Fin Rosy Barb Care Guide

The Long Fin Rosy Barb (Pethia conchonius) is a graceful and active freshwater fish admired for its flowing fins and shimmering pink-to-rosy body. Hardy and adaptable, it’s an excellent choice for both beginner and experienced aquarists looking to add elegance and movement to their community tanks.

Origin
The Rosy Barb is native to South Asia, particularly India, Bangladesh, and Nepal, where it inhabits rivers, lakes, and ponds. The long fin variety is a selectively bred ornamental strain developed for the aquarium trade.

Appearance
This variety features elongated, delicate fins and a body that glows in shades of pink, red, or gold. Males tend to be more vibrantly colored, especially during the breeding season, while females have a rounder body shape and softer tones. Adults typically reach 4–6 inches in length.

Behavior
Long Fin Rosy Barbs are peaceful yet lively schooling fish that thrive in groups of six or more. They are fast swimmers and enjoy exploring all areas of the tank. In good conditions, their colors intensify and fins flow beautifully in the current.

Tank Setup

* Minimum tank size: 30 gallons for a group.
* Provide open swimming space along with plants and décor for hiding.
* A secure lid is recommended as they can jump.
* Gentle to moderate water flow is ideal.

Water Parameters

* Temperature: 64–75°F
* pH: 6.0–7.5
* Hardness: Soft to moderately hard water

Diet
Omnivorous by nature, Long Fin Rosy Barbs accept flakes, pellets, and a variety of live or frozen foods such as bloodworms, brine shrimp, and daphnia. A balanced diet with some vegetable content helps maintain their health and coloration.

Tank Mates
They mix well with other peaceful or semi-active species such as danios, tetras, corydoras, and other barbs. Avoid slow-moving long-finned fish, as barbs may occasionally nip if underfed or kept in too small a group.

Care Tips

* Keep in larger groups to minimize fin-nipping tendencies.
* Regular water changes are essential for health and vibrant color.
* Provide both open swimming space and plant cover for balance.

Conclusion
The Long Fin Rosy Barb is a hardy, stunning fish that brings beauty and activity to any community aquarium. With its peaceful nature, flowing fins, and shimmering colors, it remains a favorite for aquarists seeking both elegance and energy in their tanks.
