⭐ HIGHLIGHT

A brilliant golden surface-dwelling fish featuring reflective scales, red fin accents, and an elongated body. Its bold coloration and active feeding behavior make it an eye-catching aquarium resident.

📝 CARE NOTES

Provide floating plants, gentle-to-moderate flow, and open areas along the surface. This species is an exceptional jumper, so the aquarium must have a tight-fitting, gap-free lid. Offer mostly floating foods and remember that any fish small enough to fit into its mouth may be eaten.
