The whip coral goby is one of Komodo's tiniest and most endearing reef fish, a nearly transparent goby that lives its entire life perched on a single strand of whip coral. At barely 3 centimetres in length, this minuscule fish has evolved to be almost invisible — its translucent body, lined with faint internal markings, is perfectly adapted to blend with the thin, wire-like whip coral on which it sits. In Komodo, whip coral gobies are found wherever healthy wire corals grow on current-exposed reef walls and slopes, but their diminutive size means most divers pass within centimetres without ever noticing them. They feed on zooplankton that drifts past their perch, darting out to snatch individual organisms before returning to their coral home. Mated pairs share a single whip coral, with the female laying eggs directly on the coral surface. The goby's commitment to its whip coral host is lifelong — it will remain on the same coral strand for its entire adult existence, relying on the elevated position to access food carried by the current. Finding and photographing a whip coral goby is a test of observation skills and macro technique that separates dedicated critter hunters from casual reef observers.

Run your eye slowly along the length of any whip coral strand, looking for a tiny, translucent shape sitting on the surface. Their internal organs may be faintly visible as subtle lines. Once you see your first one, you will start noticing them everywhere.
