Green Belly Goby
Green Belly Goby (Lentipes ikeae) is a newly described and stunning Sicydiinae goby from clear hillstreams in Sumatra, Indonesia. Males develop vivid green to turquoise-green coloration on the belly and lower body — a striking ventral coloration pattern unusual even among the already colorful Stiphodon relatives. Described in 2014, it is one of the more recently discovered hillstream gobies to enter the aquarium hobby.
Feeding & Care Tip: Live algae and biofilm on rocks and glass are the primary food source — established algae growth is essential. Supplement with Hikari Mini Algae Wafers placed on rocks and blanched vegetables. Hikari Frozen or Freeze-Dried Baby Brine Shrimp very sparingly.
⚠ Algae Requirement: Like Otocinclus catfish, Stiphodon gobies are specialized algae and biofilm grazers that cannot survive without established live algae growing on rocks, glass, and hardscape. A tank without significant algae and biofilm growth will not sustain these fish regardless of supplemental feeding. 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.
Stiphodon 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.
Note on Breeding: 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.
Described from clearwater hillstreams in Padang, West Sumatra. The vivid green ventral coloration is distinctive even within the Lentipes genus. A genuinely rare collector's find.
