Yasha Goby

The Yasha Goby (Stonogobiops yasha) is a tiny, brilliantly striped shrimp‑goby known for its red‑orange bands, tall white dorsal fin, and its iconic symbiotic partnership with pistol shrimp. It’s peaceful, reef‑safe, and one of the most captivating nano‑reef fish available. 🐟 Identity & Key Facts • Scientific name: Stonogobiops yasha • Common names: Yasha Goby, Yasha White Ray Shrimp Goby, Orange‑Striped Shrimp Goby • Adult size: ~2–2.5 inches (≈6 cm) • Lifespan: 3–5 years (typical in captivity) • Origin: Western Pacific — Japan, Indonesia, Ryukyu Islands, GBR • Care level: Moderate; best in stable, mature nano reefs 🎨 Appearance • Slender white body with bold red‑orange horizontal stripes. • Dramatically elongated first dorsal fin ray—a banner‑like “flag” that makes the species instantly recognizable. • Yellow facial accents and translucent fins with subtle blue/green edging (varies by lighting). 🌍 Natural Habitat • Found on sandy bottoms near reef slopes at 5–40 m depth. • Lives in shared burrows with Alpheus pistol shrimp. 🤝 Symbiotic Behavior (Its Signature Feature) The Yasha Goby forms a mutualistic partnership with pistol shrimp—most commonly Alpheus randalli. • The shrimp digs and maintains the burrow but has poor eyesight. • The goby stands guard, touching the shrimp with its tail and signaling danger with rapid flicks. • Both retreat into the burrow when threatened. This is one of the most fascinating natural behaviors you can display in a home reef. 🏡 Aquarium Requirements • Minimum tank size: 10 gallons (20+ gallons ideal for shrimp pairing and tankmates) • Substrate: • Fine sand (≥2") for burrowing • Add small rubble for shrimp tunnel reinforcement • Aquascape: • Stable rock structures resting on the tank bottom (not on sand) to prevent collapses • Plenty of hiding spaces • Water parameters: • Temp: 75–79°F • Salinity: 1.020–1.026 • pH: 8.1–8.4 • Flow: Low to moderate • Lid: Mandatory — Yasha Gobies are excellent jumpers. 🍽️ Diet Carnivore — feeds on tiny crustaceans and zooplankton near the burrow. • Frozen mysis • Enriched brine shrimp • Cyclops • Finely chopped seafood • Small sinking pellets Feed 2–3× daily, ideally target‑fed near the burrow so food isn’t stolen by faster fish. 🪸 Compatibility • Reef‑safe and extremely peaceful. • Best with small, non‑aggressive tankmates: • Firefish • Small clownfish • Other peaceful gobies (different species) • Pistol shrimp (highly recommended) • Avoid: • Large wrasses • Hawkfish • Dottybacks • Any aggressive or boisterous feeders 🧬 Breeding • Can spawn in captivity inside the shared burrow. • Male guards eggs until hatching. • Larvae are extremely small and require specialized planktonic foods—breeding is possible but challenging. 📝 Why It’s a Customer Favorite For Seahorse Aquarium & Supply, the Yasha Goby is a perfect nano‑reef showcase species: • Tiny bioload • Stunning coloration • Peaceful and reef‑safe • The goby–shrimp symbiosis is a guaranteed crowd‑pleaser
