Males develop vivid red to orange-red coloration in the tail region contrasting with a darker body — a striking two-tone effect. One of the larger Sicyopterus species. Like all Sicydiinae gobies, it is an amphidromous species with a life cycle that requires marine conditions for larval development — captive breeding is not possible. Wild-caught specimens require established algae growth and pristine, well-oxygenated water.\u003c\/p\u003e\u003cp style=\"font-family:Georgia,serif;font-size:1.05em;line-height:1.8;margin-bottom:16px;background-color:#e0f0f8;border:1px solid #b0d0e8;padding:14px 18px;color:#0a2a3a;\"\u003e\u003cstrong\u003eFeeding \u0026amp; Care Tip:\u003c\/strong\u003e \u003cstrong\u003eLive algae and biofilm\u003c\/strong\u003e on rocks and glass are the primary food source — established algae growth is essential before adding this fish.

Allow algae to establish thoroughly before adding Stiphodon. Hikari Mini Algae Wafers placed directly on rocks supplement but do not replace live algae growth. Blanched zucchini or spinach on rocks provides additional plant matter.\u003c\/p\u003e\u003cp style=\"font-family:Georgia,serif;font-size:1.05em;line-height:1.8;margin-bottom:16px;color:#2c2c2c;\"\u003eStiphodon gobies inhabit clear, fast-flowing, well-oxygenated hillstreams with rocky substrate covered in algae and biofilm. The aquarium should replicate these conditions: strong filtration, good water movement, rocky substrate and hardscape with established algae growth, and pristine water quality. These fish are sensitive to elevated nitrates and should never be added to immature aquariums. Males are territorial with each other but peaceful with other species.\u003c\/p\u003e\u003cp style=\"font-family:Georgia,serif;font-size:1.05em;line-height:1.8;margin-bottom:16px;color:#2c2c2c;\"\u003e\u003cstrong\u003eNote on Breeding:\u003c\/strong\u003e Stiphodon gobies have an amphidromous life cycle — adults live and spawn in freshwater streams, but the newly hatched larvae drift downstream to the ocean where they spend the first weeks developing in marine conditions before migrating back upstream into fresh water. This remarkable journey sometimes involves climbing waterfalls using their modified pelvic fins as suction cups. Captive breeding is not possible due to this marine larval stage.\u003c\/p\u003e\u003cp style=\"font-family:Georgia,serif;font-size:1.05em;line-height:1.8;margin-bottom:24px;color:#2c2c2c;\"\u003eA specialist fish for the hillstream goby enthusiast.
