Gumdrop Spotted Croucher

Gumdrop Spotted Croucher Goby (Tomiyamichthys oni): Tiny, compact goby with a “gumdrop” body shape and bold spotted pattern Typically reaches only 1–1.5 inches, making it one of the smallest gobies in the trade Known for perching behavior and short, hopping movements rather than active swimming Excellent nano‑reef inhabitant with tons of personality Origin & Habitat Native to the Western Pacific, including Japan and surrounding regions Found in shallow rubble zones, sandy pockets, and sheltered reef edges Often perches near small crevices or burrows for security Temperament & Reef Safety Peaceful and fully reef‑safe Does not harm corals or invertebrates May be shy at first but becomes bold once settled Ideal for nano tanks with gentle tankmates Tank Requirements Suitable for nano tanks as small as 10 gallons Provide rockwork, caves, and small hiding spots Gentle flow preferred — avoids strong currents Stable water parameters: 72–78°F, pH 8.1–8.4, salinity 1.023–1.025 Diet Carnivore Eats mysis shrimp, enriched brine, copepods, and finely chopped seafood Accepts high‑quality micro‑pellets once acclimated Benefits from small, frequent feedings Compatibility Works well with peaceful nano fish and shrimp Avoid aggressive or boisterous tankmates that may outcompete it Can be kept singly or in small groups if space allows Why Hobbyists Love It Adorable gumdrop shape and spotted pattern Unique perching behavior and quirky movements Perfect for nano reefs and small display tanks Hardy once established and full of charm
