Lubricogobius exiguus
Tiny yellow gobies hovering over rubble in Luzon and Sulawesi, year-round in 21-29C water. Here's where to spot them.
A tiny yellow-orange fish, barely 3cm, with a soft rounded body and no strong pattern beyond an overall wash of colour and a pair of pale blue eye markings. It hovers in place rather than perching flat on the substrate like most gobies, tail down and head slightly raised, usually just above a burrow or bottle it's claimed as home. There's no bold stripe or spot to key on, it's the shape, the hover, and the plain gold-yellow colour together that give it away.
Look for it hovering motionless a few centimetres above a burrow entrance, shell, or bit of rubble, retreating inside the instant it feels threatened. It rarely strays far from that shelter, making it a patient subject for macro photographers once you find one and hold still. Divers report it as uncommon at most sites, so a slow, deliberate scan of muck substrate is usually needed rather than expecting one to swim into view.
It nests inside empty shells, bottles, or burrows rather than on open substrate, which is part of why muck-diving sites with human debris on the bottom are so productive for finding one.
No clear seasonal pattern shows up in the sightings, and with a comfortable range of roughly 21 to 29C it's present on these reefs year-round. Plan around good muck-diving conditions at your chosen site rather than a particular month.
Most reliably logged in the Philippines, especially around Luzon and the Visayas, with a smaller but steady presence in Indonesia's Sulawesi region. Sites tend to be muck or rubble-bottomed rather than hard coral reef, since this goby favours debris and small burrows over coral heads.
Mapping where Yellow Pygmy-goby is logged…
The strongest sightings come from the Philippines, particularly Luzon and the Visayas, with additional records from Sulawesi in Indonesia. Look for muck or rubble dive sites rather than open coral reef.
There's no detected season in the sighting data, and its temperature range of roughly 21 to 29C spans typical year-round conditions on these reefs, so it can turn up any month.
Look for a tiny, roughly 3cm fish in plain yellow-orange with pale blue eye markings, hovering just above a burrow or piece of debris rather than resting flat on the bottom. The hovering posture near a shelter is the biggest giveaway.
They stay tiny, topping out around 3cm, which makes them a favourite subject for macro photographers rather than a fish you'll spot from a distance.
It sets up home inside empty shells, bottles, or small burrows on the sea floor, hovering just above the entrance and darting inside the moment it feels threatened.
