Golden Wonder Killifish
Aplocheilus lineatus, also known as the Striped Panchax, is a larger killifish native to India and Sri Lanka. The ‘Golden Wonder’ variety has been line-bred for more intense coloration compared to wild ancestors.
These fish are generally peaceful but males can become territorial with one another. Their large mouths allow them to consume prey larger than expected—Neon tetras, for example, may be at risk of being eaten.
Golden Wonder Killifish spend most of their time near the water surface, making them an excellent choice for filling upper tank areas that are often underutilized.
These are young adults, typically measuring 1.5 to 2 inches in length.

Great for filling the top part of the tank. The coloration is vibrant and the fish are active. Just make sure not to mix them with small schooling fish like neon tetras.

The golden color stands out well in my aquarium. They’re not aggressive, but I noticed males start to fight when kept in groups. I now keep them alone or with larger, calm fish.

I bought these for a beginner tank. They’re easy to care for and stay near the surface, which helps with visibility. The color is intense and eye-catching.
