Long-finned goby
📖 Overview
Adults occur in areas of fine sand and shallow lagoon reefs at depths less than 3 m, rarely at depths greater than 6 m. Adults usually in pairs, constructing burrows under rubble. Monogamous . They feed on small invertebrates (e.g. copepods, amphipods, ostracods, nematodes, and foraminiferans) by sifting mouthfuls of sand.

🥚 Reproduction
After spawning, a paired female constructs a mound on the burrow made up of dead coral fragments while the male watches over the eggs in the burrow . The mound promotes water-exchange in the burrow which helps the male in tending the eggs . The amount of female parental investment is displayed by the height of the constructed mound . Consequently, larger females build higher mounds which affects male mating preference . Monogamous mating is observed as both obligate and social .
