Panda Garra Breeding Guide

How to breed Garra flavatra: sexing by tubercles, conditioning broodstock, spawning setup with high flow, and rearing the transparent eggs and fry.

Overview

Garra flavatra is an algae-grazing cyprinid from Myanmar that has been bred commercially since 2008 at Hein Aquarium in Yangon to reduce pressure on wild stocks. The IUCN Red List classifies the species as Vulnerable (2010). Home breeding is considered advanced because it depends on well-oxygenated, fast-flowing water and careful conditioning.

Sexing

Sexing relies on breeding condition. Mature males develop a series of noticeable tubercles on the head, along the lateral line and around the caudal peduncle, and are slimmer than females. Females are correspondingly fuller-bodied when carrying eggs.

Conditioning

In the documented commercial protocol, broodstock are conditioned on algae-enriched dried foods, live Tubifex worms and the occasional chopped earthworm. High water flow is maintained throughout conditioning, matching the species' preference for well-oxygenated, current-rich water.

Breeding Setup

Individual pairs are moved to 80-litre tanks. Tube-well water with a conductivity around 80 µS and a pH close to neutral is delivered through overhead spray bars to create strong flow and oxygenation. The species otherwise tolerates a temperature of 20-26 °C and pH 6.5-7.5.

Spawning Behavior & Trigger

Seasonal spawning occurs during the months of May to July. Eggs are deposited in the early morning. The combination of cooler, soft, flowing water delivered by spray bars and the rich conditioning diet acts as the spawning trigger.

Egg & Fry Care

Eggs are totally transparent with a diameter of approximately 1.5-1.8 mm and hatch in 24-30 hours. Fry then absorb their yolk sac for a further 72 hours. They are first fed an egg-yolk suspension, accept Artemia nauplii after roughly one week, and move onto the adult diet once they reach 15 mm or more.
