Common name: Caesiura pygmygoby

General information

The Blue-lined Pygmy Goby, scientifically known as Trimma caesiura, is a diminutive and colorful fish that is a favorite among nano-reef enthusiasts. Its vibrant blue lines and orange hues make it a visually appealing addition to small aquariums. This species is known for its peaceful demeanor and can often be seen perching on rockwork or coral branches.

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.
