Fireline Devario (Devario sondhii) is a lively small shoaling fish for aquarists who want constant movement in the upper and middle levels of the aquarium. Its slim body, metallic sheen and orange-red side line make it stand out best as a group rather than as a single fish.
This is a peaceful, active species, but it is not a slow display fish. Give it swimming room, clean well-oxygenated water and a secure lid. It suits mature planted community aquariums where tank mates are calm but not delicate enough to be unsettled by fast danio-style movement.
Quick facts
| Scientific name | Devario sondhii |
|---|---|
| Common name | Fireline Devario |
| Adult size | About 4-6.5 cm |
| Minimum aquarium | 75 litres; longer tanks are better for a shoal |
| Temperature | 18-24°C preferred |
| pH | 6.0-7.5 |
| Temperament | Peaceful, fast and social |
| Diet | Quality flakes, micro pellets and small frozen foods |
Care and setup
Keep Fireline Devario in a group of at least six. A longer aquarium lets the shoal turn and accelerate naturally, while plants around the sides and back give security without blocking the swimming lane. Moderate flow, good oxygenation and regular maintenance are more important than a complicated layout.
The species is often happiest in cooler tropical conditions, so avoid running the aquarium too warm for convenience. Stable water in the 18-24°C range is a sensible target. Use a tight lid because active Devario can jump, especially during feeding or when startled.
Feeding
Feed small portions that the group can clear quickly. A fine community flake or micro pellet works as the staple, with frozen cyclops, daphnia, brine shrimp and similar small foods added for variety. Several light feeds are better than one messy feed in a fast shoaling aquarium.
Compatibility
Good tank mates include similar-sized rasboras, danios, white clouds, peaceful barbs, small loaches and Corydoras that enjoy comparable water. Avoid slow long-finned fish, very timid species, predators and any aquarium where the fast top-water movement would cause stress.
Arrival and guarantee

Frequently Asked Questions
How many Fireline Devario should I keep?
Keep at least six. A group spreads nervous energy, improves confidence and shows the natural shoaling behaviour.
Is Fireline Devario suitable for beginners?
It can suit careful beginners with a mature aquarium, stable water, a secure lid and enough swimming space.
What temperature is best?
A cooler tropical range around 18-24C is preferred. Avoid overheating the tank just because other tropical fish tolerate it.
What should I feed them?
Use fine flakes or micro pellets as the staple, then add small frozen foods such as daphnia, cyclops or brine shrimp.
How are live fish delivered?
When in stock, they are packed for a licensed live-animal courier service and covered by the Live Arrival Guarantee when the receiving rules are followed.

I have a small group of long finned mountain minnows. So was delighted to be able to order ten of this variety to increase the genetics in my tank . The ones I recieved are healthy but it’s to early to give a verdict on wether they are of a long finned type since they are small currently.

100% success travel and "installation". Pleased with quality of purchase. The Siamese fighter a bit "shy" so have not yet seen him at his best yet but looking good. Happy customer. GG
