Ideal Tank Size
A 10-gallon tank is the minimum for a small group of Chili Rasboras. They are schooling fish and like to swim in groups of six or more. A larger tank offers more swimming space and stability in water quality. Avoid overcrowding to reduce stress and aggression.
Water Conditions

Plant And Decoration Tips
Dense plants create hiding spots and mimic their natural habitat. Floating plants help soften the light in the tank. Use dark substrate to highlight their red colors. Add smooth rocks or driftwood for extra shelter. Avoid sharp decorations that can harm their delicate fins.

Diet Preferences
Chili Rasboras like small, live foods. They enjoy daphnia, brine shrimp, and mosquito larvae. These foods help their colors shine bright. Flake and pellet foods also work well. Choose high-quality flakes made for small fish. They eat tiny bits easily. Variety is key to a balanced diet.
Feeding Schedule
Feed Chili Rasboras twice a day. Offer only what they can eat in two minutes. Overfeeding can pollute the tank water. Remove leftover food quickly to keep the tank clean. Young fish may need more frequent feedings. Observe their behavior to adjust feeding times.

Compatibility With Other Fish

Breeding Chili Rasboras
Breeding Chili Rasboras can be a rewarding experience for fish enthusiasts. These small, colorful fish have simple breeding habits. They do not require complex conditions, making them ideal for beginners. Understanding their needs helps increase the chance of success in breeding.
Breeding Setup
Use a small tank of about 10 gallons for breeding. Keep the water temperature between 78°F and 82°F. Soft, slightly acidic water is best. Add fine-leaved plants or spawning mops for egg laying. Use a sponge filter to keep water clean without harming eggs. Keep lighting low to reduce stress for the fish.
Spawning Process
Chili Rasboras spawn in the early morning hours. Males show brighter colors to attract females. They gently chase females near plants or spawning mops. Females release eggs one by one on plant leaves. Males fertilize eggs immediately after they are laid. Remove the adult fish after spawning to protect the eggs.
Raising Fry
Eggs hatch in about 24 to 36 hours. Keep the tank dark to protect the fragile fry. Feed newly hatched brine shrimp or liquid fry food. Offer small meals several times a day. Change water regularly to keep it clean. Fry grow quickly and develop colors within weeks.

Disease Prevention
Clean water is the best way to prevent diseases. Change the tank water regularly and remove leftover food. Keep the tank temperature steady between 22-26°C (72-79°F). Avoid overcrowding the tank to reduce stress and spread of germs. Quarantine new fish before adding them to the main tank. Use a good filter to keep water clear and healthy.
Treatment Options
Look for signs like faded color, slow movement, or spots on the fish. Use aquarium salt to treat minor infections and improve gill function. Medications for bacterial or fungal infections are available at pet stores. Follow the instructions carefully to avoid harming the fish. Remove sick fish to a separate tank to stop disease spread.
