🐟 Sicyopus Zosterophorus – A Vibrant Gem for Advanced Aquarists

The Sicyopus zosterophorus, commonly known as the Zosterophorus Goby, is a stunning freshwater goby species prized for its vibrant coloration, active personality, and rare appearance in the aquarium trade. Native to fast-flowing streams and rivers of Southeast Asia, this goby is a top choice for aquarists looking to add a unique, lively species to a well-maintained tank. With its iridescent stripes and torpedo-like shape, it’s both a visual highlight and a fascinating species to observe in motion.

Due to its specific care requirements, this species is recommended for intermediate to advanced aquarists who can replicate its natural environment and maintain optimal water quality.

✅ Key Features & Benefits

• Bright, Electric Colors
  Males display striking iridescent blues, greens, and orange markings—especially during display behavior or breeding activity. Females tend to have more muted tones but still possess a sleek, beautiful profile.

• Ideal for River-Style Aquascapes
  Naturally found in fast-moving, oxygen-rich freshwater streams, the Zosterophorus Goby thrives in setups with high water flow, smooth stones, and sand or fine gravel substrate. Ideal for aquascapers who enjoy building river biotopes.

• Small & Peaceful
  Reaching only about 2.5–3 inches (6–7 cm) in length, it’s a peaceful fish suitable for nano tanks or community aquariums with compatible tank mates.

💧 Water Parameters & Tank Setup

• Use a canister or powerhead filter to replicate stream-like conditions.

• Add rounded river rocks, fine sand, and driftwood to mimic natural habitat.

• Keep the tank well-oxygenated with consistent water changes and aeration.

🍽️ Feeding Habits

• Carnivorous – in nature, they graze on biofilm, small invertebrates, and benthic organisms.

• In captivity, they accept:

  • Frozen foods like daphnia, brine shrimp, cyclops

  • Live food such as micro worms or blackworms

  • May accept high-quality sinking carnivore pellets over time

• Not suitable for flake-only diets. Feeding small amounts 2–3 times daily is ideal.

🧠 Care Tips

• Requires stable, clean water conditions—ammonia and nitrite must always be 0 ppm.

• Not recommended for beginners due to sensitivity to water quality and diet specificity.

• Use a tight-fitting lid—they can jump if startled or during active foraging.

• Keep in groups of 3–6 to reduce aggression and encourage natural behavior.

• Breeding in captivity is possible but rare and requires brackish water during early fry development.
