Indian Sunset Barb
The Indian Sunset Barb (Pethia setnai) is a colorful, peaceful freshwater barb native to the Western Ghats of India. Also known as the Sunset Barb, Narayan Barb, or Indigo Barb, this attractive schooling fish develops warm orange, red, and golden tones as it matures.
Unlike some more boisterous barb species, the Indian Sunset Barb is generally well suited to peaceful community aquariums when maintained in a proper group. Its active swimming behavior, compact adult size, and striking coloration make it an excellent choice for planted and stream-style freshwater aquariums.

Recommended Aquarium Size
A 20-gallon-long aquarium or larger is a practical minimum for a small group of Indian Sunset Barbs.
Because they are active schooling fish, horizontal swimming space is more useful than excessive tank height. Larger aquariums are recommended for bigger schools or mixed community setups.
Recommended Water Parameters
- Temperature: Approximately 72–79°F
- pH: Approximately 6.0–7.5
- Water Hardness: Soft to moderately hard
- Ammonia: 0 ppm
- Nitrite: 0 ppm
- Nitrate: Kept low through routine maintenance
Indian Sunset Barbs appreciate clean, well-oxygenated water with moderate circulation. Stable water quality is more important than reaching one exact pH or hardness value.
Schooling and Behavior
Indian Sunset Barbs are social fish and should be maintained in a group of at least six. Larger groups of eight to ten or more can help the fish feel more secure and encourage stronger coloration and more natural behavior.
When kept in sufficient numbers, they are generally peaceful and spend much of their time swimming through the middle levels of the aquarium.
Aquarium Setup
A natural-looking aquarium with open swimming space and plenty of cover works especially well for this species.
- Use a fully cycled freshwater aquarium
- Provide good filtration and oxygenation
- Allow open midwater swimming space
- Add live plants around the sides and rear
- Use smooth rocks, pebbles, or driftwood for structure
- Provide moderate water movement
- Perform regular partial water changes
- Use a secure aquarium lid
Feeding
Indian Sunset Barbs are omnivores and readily accept a variety of aquarium foods.
A balanced diet may include:
- Quality tropical flakes
- Small sinking or slow-sinking pellets
- Micro pellets
- Frozen brine shrimp
- Frozen daphnia
- Bloodworms as an occasional food
- Spirulina or vegetable-based foods
Feed small portions once or twice daily, offering only what the fish can consume within a few minutes.
Compatible Tankmates
Indian Sunset Barbs are generally compatible with similarly sized peaceful community fish.
Good tankmates may include:
- Danios
- Rasboras
- Peaceful tetras
- Cherry Barbs
- Corydoras catfish
- Loaches
- Peaceful gouramis
- Small rainbowfish
- Other peaceful barbs
Avoid highly aggressive fish and extremely slow or delicate long-finned species. Even peaceful barbs may occasionally investigate or nip flowing fins, particularly if the barb group is too small.
Male vs. Female
Mature males are generally slimmer and display stronger coloration, especially during breeding condition.
Females tend to be fuller-bodied and may have more subdued coloration.
Breeding
Indian Sunset Barbs are egg-scattering fish.
Adults do not provide parental care and may eat their eggs, so breeders typically use a separate spawning aquarium with fine-leaved plants, spawning mops, or mesh that allows eggs to fall away from the adults.
After spawning, the adults should be removed if the goal is to raise fry.
Important Care Notes
- Keep in groups of at least six.
- Do not add to an uncycled aquarium.
- Maintain good oxygenation and water quality.
- Provide plenty of open swimming space.
- Avoid consistently high nitrate levels.
- Choose similarly peaceful tankmates.
- Never release aquarium fish into local waterways.
Frequently Asked Questions
How large do Indian Sunset Barbs get?
Adults generally reach approximately 2.5–3 inches.
Are Indian Sunset Barbs peaceful?
Yes. They are considered one of the more peaceful barbs, especially when kept in an appropriately sized group.
How many should I keep together?
Keep at least six, although eight to ten or more is even better when aquarium space allows.
Can they live in a community aquarium?
Yes. They are well suited to peaceful community tanks containing similarly sized fish with compatible water requirements.
Do they need a heater?
In most homes, a heater is useful for maintaining a stable temperature within their preferred range, particularly when room temperatures fluctuate.
Are they fin nippers?
They are generally less prone to fin-nipping than many other barbs, but keeping an adequate school and avoiding very long-finned tankmates is still recommended.
Do they need strong water flow?
Moderate circulation and good oxygenation are beneficial because the species naturally occurs in clear, flowing waters.
