Bumblebee Goby (Brackish)

Brachygobius xanthozonus

Gobies & Gudgeons

4.5 cm Mostly Peaceful

A miniature, bottom-dwelling goby famous for its striking black and yellow stripes. While they are often sold as freshwater fish and can survive in it temporarily, they are highly susceptible to fungal infections in fresh water and truly require a brackish setup (SG 1.002-1.005) to thrive long-term. They are notoriously picky eaters, often ignoring flakes in favor of live or frozen foods (like bloodworms or brine shrimp).

Knight Goby

Stigmatogobius sadanundio

Gobies & Gudgeons

9 cm Semi-Aggressive

A distinct, high-bodied goby found in estuaries across South Asia. Unlike most bottom-dwelling gobies, the Knight Goby frequently hovers in the water column. While often sold as freshwater fish, they thrive best in slightly brackish water (SG 1.003-1.005) or very hard, alkaline freshwater. They are territorial and notorious fin-nippers, making them poor tankmates for Guppies or Bettas.

Neon Blue Goby

Stiphodon atropurpureus

Gobies & Gudgeons

5 cm Mostly Peaceful

A stunning, specialized freshwater goby native to fast-flowing hill streams in Asia. Males display brilliant neon blue metallic coloration, while females are striped. They are specialized biofilm grazers ('Aufwuchs' eaters) and require mature tanks with established algae/biofilm stones. They are obligate stream dwellers requiring high oxygen and strong flow.

Peacock Gudgeon

Tateurndina ocellicauda

Gobies & Gudgeons

6 cm Peaceful

A stunning, peaceful freshwater sleeper goby from Papua New Guinea. Known for their vibrant blue, red, and yellow colors, they are excellent nano-tank inhabitants. They are not true gobies (they lack fused pelvic fins) and are exclusively freshwater. They prefer slow-moving water, dense vegetation, and small caves (like PVC pipes or smooth stones) for spawning.

Violet Goby (Dragon Goby)

Gobioides broussonnetii

Gobies & Gudgeons

50 cm Peaceful

Often misunderstood due to its terrifying 'Dragon' appearance and sharp teeth, the Violet Goby is actually a gentle, nearly blind scavenger and filter feeder. It uses its teeth to scrape algae, not to bite fish. It requires brackish water to thrive long-term and fine sand to sift through for food. It is not a predator.
