Rhinogobius maxillivirgatus – ~4 cm Mini Stream Goby

Description

The Maxilli-Striped Goby is a newly described and exceptionally small freshwater species, reaching just ~4 cm in total length. Native to a secluded tributary of the Yangtze (Changjiang) River in Anhui, China, this goby is instantly recognizable by its 5–6 serrated longitudinal stripes and the pair of bold oblique bars just behind its upper jaw—features that inspired its scientific name. In males, numerous red spots adorn the gill membranes, enhancing its already charming appearance. Due to its very limited distribution and recent scientific description (2018), this goby remains rare in the aquarium hobby and highly prized by specialist enthusiasts.AquaInfoReefs.com

Care Instructions

• Tank Setup:

  • A small tank (~20–25 L) is sufficient for a nano-style stream biotope. Use fine gravel or sand with smooth stones to recreate its natural habitat.

• Water Conditions:

  • Keep water clean and well-oxygenated using moderate flow. Ideal temperature: 18–22 °C.

  • Maintain stable conditions with neutral to slightly acidic pH.

• Diet:

  • Omnivorous and carnivorous tendencies—offer micro-live foods like daphnia, brine shrimp, and finely chopped invertebrates.

• Behavior & Social Needs:

  • Likely peaceful with mild territoriality. A small group is ideal, but provide ample hiding spots to reduce competition.

• Notes:

  • Given its recent discovery and scarce trade presence, breeding or obtaining fish may be limited to advanced hobbyists and specialized networks.
