stiphodon rutilaureus

Stiphodon rutilaureus, commonly known as the Red-Gold Stiphodon, is a species of freshwater goby prized for its stunning colors and fascinating behavior. Keeping this fish successfully requires careful attention to its specific needs. Here’s a guide to help you care for them:

Tank Setup

1. Tank Size: A minimum of 10 gallons for a small group (35 individuals). A larger tank (20+ gallons) is ideal for better stability and space.
2. Substrate: Fine sand or smooth gravel, as these fish often graze on algae and biofilm on the substrate.
3. Water Flow: Moderate to strong water flow is essential. Stiphodon gobies are naturally found in fast-flowing streams and require similar conditions to thrive.
4. Decoration:
   • Smooth rocks and boulders where algae and biofilm can grow.
   • Driftwood and aquatic plants to mimic their natural habitat and provide hiding spots.

Water Parameters

• Temperature: 2226C (7279F)
• pH: 6.57.5 (neutral to slightly alkaline)
• Hardness: Soft to moderately hard water (515 dGH)
• Water Quality: Maintain pristine water conditions with regular water changes (2530% weekly). Use a strong filter to provide oxygenation and flow.

Diet

Stiphodon rutilaureus primarily feeds on algae and biofilm in the wild. In captivity:

• Offer algae wafers, spirulina flakes, or other high-quality herbivore-specific foods.
• Supplement with blanched vegetables like zucchini or spinach.
• Occasional live or frozen foods (e.g., daphnia, brine shrimp) can be offered but should not make up the bulk of their diet.

Behavior and Tankmates

• Social Behavior: They are peaceful and thrive in groups. A group of 36 individuals is recommended.
• Tankmates: Choose small, peaceful fish that won’t outcompete them for food, such as:
  • Small rasboras or tetras
  • Otocinclus catfish
  • Shrimp (e.g., Neocaridina or Caridina species)
• Avoid aggressive or territorial fish that may stress them.

Breeding

Breeding in captivity is rare but possible. Key points:

1. Provide a separate breeding tank with similar water parameters.
2. Include smooth rocks for egg deposition.
3. Eggs hatch into larvae that require brackish water to develop before returning to freshwater.

Additional Tips

• Stiphodon gobies are more active and display better coloration in well-maintained tanks with ample algae growth.
• Avoid sharp decorations to prevent injuries to their delicate bodies.
• Provide adequate hiding spaces to make them feel secure.
