Threadfin Rainbowfish need a tank of at least 60 litres. This size lets them show off their colours and swim together. Keeping the water’s pH, temperature, and hardness right is also vital.

Filtration and Lighting Requirements

A good filter is essential for clean water. Pick one that can filter 4-6 times the tank’s volume each hour. Also, use lighting that’s not too bright but still natural.

These freshwater fish have specific needs that are important for their well-being in captivity.Threadfin Rainbowfish love to eat a mix of plants and proteins. Their diet should include high-quality flakes or pellets, live or frozen foods, and some plant matter.

• High-quality flakes or pellets formulated for tropical community fish should make up the staple of their diet, providing a balance of essential nutrients.
• Live or frozen foods, such as brine shrimp, daphnia, and bloodworms, are excellent protein sources that bring out their vibrant colours.
• Supplementing their diet with occasional blanched vegetables, like spinach or zucchini, can help meet their plant-based nutritional needs.

Feeding them small, frequent meals is best. This is because they naturally graze and it prevents overfeeding, which can harm their health.
