迎接三角燈前需要了解的7件事

1. 1Keep them in a school

   Kept alone or in twos or threes, Harlequin Rasboras tend to hide and rarely show their natural behavior. Bring home at least six to ten at once so they can form the tight, shimmering schools they're known for.

2. 2Peaceful and community-friendly

   Harlequin Rasboras are peaceful and rarely bother other fish, making them a good match for other calm, small tankmates. Avoid housing them with aggressive or much larger fish, which can stress them into hiding.

3. 3Shines in a planted tank

   Their orange body and black triangular marking stand out beautifully against a backdrop of green plants. Adding plants and driftwood for cover also helps them feel secure and settle in.

4. 4Feeds on flake and frozen food

   They readily eat both flake or pellet food and frozen food, and are not picky eaters. Because their mouths are small, offer small-sized food in a few light feedings throughout the day.

5. 5Sensitive to water changes

   Sudden shifts in water chemistry or temperature can stress this species. Take time to acclimate new arrivals gradually, and keep up with regular partial water changes afterward.

6. 6Lifespan of 3-5 years

   With a stable environment, Harlequin Rasboras typically live around three to five years. Consistent water conditions and regular feeding go a long way toward a long, healthy life.

7. 7Breeding takes some care

   They scatter eggs among fine-leaved plants, but breeding them successfully at home takes fairly specific conditions. If you're not aiming to breed them, a standard, well-maintained setup is all you need.
