Amur Goby (Rhinogobius brunneus) – ~6 cm

The Amur Goby is a graceful and robust freshwater goby native to East Asia—spanning rivers from Japan and Korea to Taiwan and China. Reaching nearly 6 cm, its distinctive features include a slender brown body often bearing vertical bands, an eye-stripe from the snout, and a bright orange patch at the base of the tail. Males display ornate patterns: red-barred dorsal fins, wavy orange tail stripes, and scattered orange-red spots on the cheeks—creating a visually complex and engaging appearance.

Care Instructions

• Tank Setup:

  • Use a medium-sized tank (at least 60 × 30 cm base) with fine sand or small pebbles and smooth stones.

  • Incorporate rocks or driftwood to create hiding spots and perching areas, mimicking their natural riverbed habitat.

• Water Conditions:

  • Keep water clean and well-oxygenated; moderate flow is beneficial.

  • Maintain temperature between 16–20 °C (61–68 °F).

  • Neutral to slightly alkaline pH; moderately soft to soft water is acceptable.

• Diet:

  • Omnivorous: accepts small live or frozen foods (like daphnia, brine shrimp), plus high-quality flakes or micro pellets.

• Behavior & Tankmates:

  • Generally peaceful, though males may exhibit light territorial behavior; ample hiding places help minimize stress.

  • Best kept with similar-sized, non-aggressive species.

• Maintenance:

  • Weekly water changes of 30–50% are recommended to maintain clarity and water quality.
