Golden Red Goby (Stiphodon Rutilaureus)

A golden goby that scales waterfalls on suction-cup fins.

Add a flash of golden-red colour to your mature stream-style aquarium with the peaceful Golden Red Goby—an algae-grazing freshwater goby for experienced keepers.

• Water conditions: The Golden Red Goby (Stiphodon rutilaureus) is a riverine species that thrives in clean, well-oxygenated freshwater with a steady, moderate-to-strong current. Aim for a temperature of 22–26°C (72–79°F), pH around 6.8–7.8, and general hardness of roughly 5–12 dGH, although stability is far more important than chasing an exact number. Ammonia and nitrite must remain at zero, and nitrate should be kept low—ideally below 20 ppm—through regular water changes and sensible stocking. These gobies are sensitive to fluctuating parameters and poor water quality, so only add them to a mature, fully cycled aquarium with plenty of biological filtration and surface agitation. A powerhead or stream pump creating gentle but constant flow across rounded rocks is ideal. Keep them in freshwater; do not add aquarium salt unless specifically advised, as adults are freshwater residents. Avoid sudden temperature swings and ensure the filter intake is covered so curious gobies cannot be trapped.
• Suitable tank mates: Peaceful, small community fish make the best companions. Think micro rasboras such as Boraras species, small Trigonostigma rasboras, modest-sized tetras, and calm nano danios that will not bully or outcompete the goby. Other peaceful bottom-dwellers—such as small loaches, Otocinclus catfish in a large mature tank, and Amano shrimp—can work well, provided there is enough biofilm and grazing space for everyone. Avoid large or boisterous cichlids, goldfish, aggressive barbs, fin-nippers, and any fish large enough to view the goby as food. Crayfish and other predatory invertebrates should also be avoided. Golden Red Gobies are generally peaceful with their own kind, but they can be territorial in cramped quarters; keep a small group only in a generously sized stream-style setup with multiple rock crevices and visual breaks. As with any livestock, quarantine new arrivals and observe tank dynamics closely.
• Feeding habits: This is an aufwuchs grazer, not a typical meat-eating bottom feeder. In the wild it rasps algae and biofilm from rocks, so an established aquarium with visible biofilm and soft green algae is essential—especially during the first few weeks. Do not expect a new, spotless tank to sustain them. Supplement natural grazing with spirulina-based algae wafers, Repashy Soilent Green or similar gel foods, blanched zucchini, cucumber, spinach, and nori. Offer small portions several times daily because gobies have small stomachs and graze continuously. They may accept tiny amounts of frozen baby brine shrimp or daphnia, but high-protein foods should not form the base of the diet. Target-feed near their favourite perching rocks and remove uneaten vegetables after a few hours. If the goby looks thin or spends little time grazing, increase biofilm-friendly feeding and ensure it is not being outcompeted by faster feeders. Never rely on glass algae alone; provide flat, smooth stones where biofilm can develop.
• Care requirements: Golden Red Gobies are best suited to experienced keepers who can provide a mature, stable stream biotope. Set up the tank with smooth, rounded stones, cobbles, and caves for perching and retreating, plus a sand or fine-gravel substrate. Strong, clean flow and high dissolved oxygen are more important than elaborate decor. Keep the lid tight-fitting—these gobies can climb and jump, particularly during acclimation or if startled. Drip-acclimatise new arrivals slowly and quarantine them before introducing them to the main display. Avoid copper-based medications and use any treatment with caution. Perform regular partial water changes of around 25–30% weekly, clean filter media gently in tank water, and avoid scrubbing every rock clean so the biofilm food source remains. Keep lighting moderate to encourage algae growth without causing nuisance blooms. Observe them daily for weight loss, laboured breathing, or lethargy, and act quickly if parameters drift. With careful feeding, stable water, and peaceful companions, this striking goby can be a rewarding centrepiece for the specialist freshwater stream aquarium.
