Chili Rasbora
The Chili Rasbora is one of the smallest freshwater fish in the aquarium hobby, reaching just 1.5 to 2 cm as an adult. Its glowing red body with a dark stripe becomes especially striking when a group swims together, scattering through the tank like tiny jewels. Naturally shy and peaceful, this species feels most secure and shows its best colors when kept in a school rather than alone. Because of its tiny mouth, it needs finely sized frozen or micro pellet foods, and it can be sensitive to shifts in water quality, making it better suited to hobbyists with some prior experience. With a lifespan of around 2 to 4 years, it rewards patient, steady care.

- Very soft, slightly acidic to acidic blackwater (pH 4.5-6.5) at 22-28°C is ideal. Adding tannins brings out the best color.
- Diet & Feeding
- Because it is so small, it needs fine powdered food or frozen brine shrimp nauplii.
- Tank Mates & Compatibility
- Peaceful and tiny, so it mixes well even with shrimp such as cherry shrimp. It shines when schooling in a nano or planted tank.
- Breeding & Egg-laying
- Breeds by scattering eggs among plants. Grow fine-leaved plants densely to serve as the spawning site.

7 things to know before welcoming a Chili Rasbora
1Keep in Schools
Chili Rasboras feel safest and show their brightest colors when kept with several of their own kind. Bring home a small school rather than a single fish to enjoy their natural schooling beauty.
2Tiny Mouths, Tiny Food
At just 1.5-2 cm, they need finely sized frozen or micro pellet foods that match their small mouths. Food pieces that are too large may go untouched.
3Sensitive to Water Changes
This species can be somewhat sensitive to sudden shifts in water quality, so acclimate new arrivals slowly and carefully. Frequent, small water changes are gentler than large infrequent ones.
4Choose Tankmates Carefully
Being small and peaceful, Chili Rasboras don't do well with large or aggressive fish. Pair them with similarly gentle, small-bodied species instead.
5Provide Places to Hide
They naturally seek shelter among plants and driftwood, so a well-planted tank helps them feel secure. A bare, overly open tank can leave them stressed.
6A Lifespan of 2-4 Years
With consistent water quality and proper feeding, Chili Rasboras typically live around 2 to 4 years.
7Best for Experienced Keepers
Their sensitivity to water conditions and small feeding requirements make them better suited to hobbyists with some prior aquarium experience. Learning the basics of water chemistry beforehand helps.
