Qian Hu Fish Farm — Longkang Fishing & Aquarium

One of Southeast Asia's largest ornamental fish farms in Choa Chu Kang, where children can try longkang (drain) fishing to catch and observe ornamental fish, explore an extensive aquarium display, and learn about fish-keeping. The longkang fishing experience is consistently rated one of the most joyful hands-on animal encounters for young children in Singapore.

Farm exploration is free; guided tour and fishing packages start from $10 per person. Walk-ins welcome for the aquarium viewing areas. Open daily; farm tours are best arranged in advance via their website. A genuinely unique Singapore experience rarely found elsewhere.
