General Description
Not commonly found in the aquarium trade, Stiphodon pelewensis is closely related to S. weberi and belongs to the Gobiidae family. Often recognized by the fully-scaled belly, these small fish can reach a maximum size of 4.5cm. They exhibit specialized dietary habits as algae grazers, possessing unique mouthparts for this purpose.
Aquarium Setup
To successfully maintain Stiphodon pelewensis in an aquarium, a well-oxygenated and clean environment is crucial. A tank capacity of at least 60 liters is recommended. The setup should include a mix of gravel and sand substrate with water-worn rocks, pebbles, and aged driftwood. Strong lighting to promote algae growth is essential, and a turnover of 10-15 times the tank volume per hour is advised. Structure the tank with hiding places for multiple males, as they can be territorial. Regular water changes and algae-covered surfaces are necessary for their specialized diet.
Behaviour
Stiphodon pelewensis exhibit loose territorial behavior, with males being more territorial, especially during breeding. They can be kept in groups, preferably with one male and multiple females. These fish are known for their ability to climb and cling onto surfaces, showcasing their unique adaptations to their natural habitat.
Feeding and Diet
Primarily herbivores, Stiphodon pelewensis feed on benthic algae and associated microorganisms. While they may accept some meaty foods like bloodworms occasionally, their diet should mainly consist of algae. Maintaining a mature aquarium with ample algae-covered surfaces is crucial for their long-term health.
Reproduction & Dimorphism
Breeding behavior includes males guarding eggs after spawning, with females being highly fecund. However, successful breeding in captivity is challenging due to their complex amphidromous breeding strategy. Sexual dimorphism is pronounced in Stiphodon pelewensis, with mature males displaying dark fins and body bars, while females have a more plain appearance.
Habitat and Distribution
Near-exclusive inhabitants of short coastal streams on tropical islands, Stiphodon pelewensis is found in regions like Palau and the Mariana Islands. They prefer habitats above waterfalls or cataracts, inaccessible to many other fish species. Their distribution extends through Micronesia, with variations in stream gradients and substrate preferences based on locality.
