Aphyosemion bitteri
Aphyosemion bitteri is a tiny freshwater killifish prized by aquarists for its vivid colors, not by anglers. It inhabits slow‑moving streams and pools with dense vegetation and rarely reaches more than 2.9 cm. Though not a sport fish, it can be collected for hobby purposes using very light gear.
