Golden Wonder Killie ~ Aplocheilus lineatus

Description & Care Guide:
The Golden Wonder Killie is a captivating freshwater fish known for its vibrant golden-yellow coloration and its curious, active nature. It is a carnivorous species that thrives in well-planted aquariums with ample swimming space. While relatively easy to care for, this species is best suited for experienced fishkeepers due to its predatory instincts, especially toward smaller tank mates. Known for its hardiness and long lifespan, the Golden Wonder Killie makes a striking addition to species-specific tanks or community tanks with larger, non-aggressive fish.

Wild Habitats/Origins:
Native to South Asia, specifically India and Sri Lanka, the Golden Wonder Killie is typically found in slow-moving streams, ponds, and marshes. These habitats are often shallow and rich in organic matter, with dense vegetation and areas for the fish to hide. The species adapts to varying water conditions but thrives in clear, oxygen-rich environments where it can hunt for small invertebrates and fry.

Fun Fact:
The Golden Wonder Killie is known for its remarkable "jumping" ability, often leaping out of the water to catch prey or avoid threats, which is where its common name originates.
