Sind Danio (Devario spinosus) Breeding Guide

Breeding Devario spinosus follows the Devario egg-scattering pattern: sexing, conditioning, a dimly lit egg-trap spawning tank and rearing fry. Species-specific spawning detail is limited.

Overview

Devario spinosus is a freshwater, benthopelagic danioin native to Myanmar, reaching a maximum of about 10 cm total length. Detailed species-specific spawning reports are not published in the whitelisted sources, so the guidance below follows the breeding pattern documented across the Devario genus and is flagged as genus-based where it is not species-specific.

Sexing

Across the Devario genus, sexually mature females are rounder-bellied, less colourful and a little larger than males. The same dimorphism is the practical basis for pairing this species.

Conditioning

Following the genus approach, condition adults together on a varied diet that includes live and frozen foods until females are clearly gravid, then move a pair to a spawning tank.

Breeding Setup

As with other Devario, a dimly lit spawning tank with a mesh or marble base lets the scattered eggs fall out of reach of the adults. Keep the water slightly acidic to neutral with good oxygenation from a sponge filter, given the species' freshwater, flowing-water habitat.

Spawning Behavior & Trigger

Devario species are egg-scattering free spawners with no parental care. Species-specific trigger data for D. spinosus is not documented; the genus pattern relies on conditioning plus warmer, soft water.

Egg & Fry Care

Following the genus pattern, remove adults after spawning, expect incubation in the region of 24-36 hours, and start fry on the smallest live foods such as Paramecium before progressing to Artemia nauplii and microworm.
