Annie's Goby Care Guide
Stiphodon annieae · Freshwater Fish
What Annie's Goby look like
Annie's Goby (Stiphodon annieae) exhibits a diminutive, laterally compressed body, typically reaching a maximum adult size of approximately 1.5 inches (3.8 cm). Sexual dimorphism is pronounced; males display a striking iridescent coloration characterized by vivid blue and green hues, complemented by a contrasting orange or red head, while females are more subdued, exhibiting a brownish coloration with dark vertical bars. A notable morphological adaptation is the fusion of the pelvic fins, which form a powerful suction cup, allowing these gobies to cling effectively to rocky substrates in fast-flowing streams. Additionally, they possess a well-defined lateral line system and sharp dentition suited for grazing on biofilm and algae, further enhancing their benthic lifestyle.
Behavior & temperament
Annie's Goby is primarily a benthic species, often found in fast-flowing freshwater streams in Southeast Asia. They exhibit a social structure that is not strictly hierarchical but rather opportunistic, with males often establishing territories during the breeding season. Males engage in elaborate courtship displays to attract females, which are egg scatterers, releasing fertilized eggs among rocky crevices. Their temperament is generally peaceful, although males can display territorial aggression during breeding periods, particularly when competing for mates.
Diet & feeding
In the wild, Annie's Goby primarily feeds on algae and biofilm, making it an obligate herbivore. In captivity, they require a diet rich in spirulina and other plant-based foods to maintain their health and vibrant coloration.
Behind the name
The genus name 'Stiphodon' is derived from the Greek 'stiphē' (to be thick or dense) and 'odon' (tooth), referring to the robust dentition of these gobies. The species name 'annieae' honors the individual after whom the species is named.
