Care
Due to their small size, Blue-lined Pygmy Gobies require a well-established aquarium with stable water conditions and plenty of hiding places. They thrive in environments with live rock that offer microhabitats and a natural source of small food items like copepods. These gobies are not aggressive feeders, so care should be taken to ensure they receive adequate nutrition in a community tank setting.
Reproduction
Trimma caesiura is an egg-laying species that exhibits a fascinating reproductive behavior. The males are known to guard the eggs, which are typically deposited on the ceiling of a small cave or overhang within the aquarium. Successful breeding in captivity is possible with careful attention to water quality and feeding.
Habitat
In the wild, Blue-lined Pygmy Gobies are found in the Western Pacific, inhabiting coral-rich areas and reef slopes. They prefer environments with moderate to strong currents and are often observed at depths where light penetration supports coral growth.
