Atinaks

Atinaks is a genus of small to medium-sized fish belonging to the family Gobiidae. These fish are typically found in freshwater and brackish environments, primarily in Southeast Asia. They are characterized by their elongated bodies, two distinct dorsal fins, and a pelvic fin that is usually fused into a suction disc. The coloration of Atinaks species can vary, often featuring mottled patterns that provide camouflage within their habitats.

The diet of Atinaks generally consists of small invertebrates and zooplankton. They are often observed foraging on the substrate or in the water column. Reproduction in Atinaks involves external fertilization, with eggs typically laid on a surface and guarded by one or both parents. Their small size and relatively inconspicuous nature mean they are not extensively studied, and much of their specific behavior and ecological role is still being investigated.

Several species are recognized within the Atinaks genus, each with its own specific geographic distribution and habitat preferences. Some species may be endemic to particular river systems or regions. Due to their dependence on specific water conditions, Atinaks can be sensitive to environmental changes, making them potential indicators of aquatic ecosystem health. Their conservation status varies among species, with some facing threats from habitat degradation and pollution.
