      • Females have somewhat elongated second to fourth spines in the first dorsal fin.
      • Caudal fin with 17-18 (usually 17) segmented rays, including 15-16 branched rays.
  2. Habitat and Behavior:

    • Threadfin Gobies thrive in coastal streams with moderate to fast flow.
    • They are usually found in small, clear creeks, often within rainforests and approximately 50 km from the sea.
