Ctenogobiops tongaensis, also known as the Tonga goby, is a tiny marine goby that inhabits coral reef crevices in tropical Indo‑Pacific waters. At just 3.9 cm it is prized by photographers rather than anglers, but can be hooked by ultra‑light gear for curiosity catches.

Fishing Tips for Ctenogobiops tongaensis

  • Use a micro‑jig or tiny soft‑plastic bait and cast within a few metres of reef edges or tide‑pools.
  • Target the edges of sand patches and small crevices where the gobies shelter; a gentle jig‑and‑retrieve works best.
  • Keep the line extremely light (2‑4 lb test) and use a 4‑5 ft ultra‑light spinning rod to feel any subtle nibble.
  • Patience is key – these fish often bite on the slightest movement, so use a slow, erratic retrieve to mimic natural prey.
