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
-
Tank Size: A minimum of 10 gallons for a small group (3–5 individuals). A larger tank (20+ gallons) is ideal for better stability and space.
-
Substrate: Fine sand or smooth gravel, as these fish often graze on algae and biofilm on the substrate.
-
Water Flow: Moderate to strong water flow is essential. Stiphodon gobies are naturally found in fast-flowing streams and require similar conditions to thrive.
-
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: 22–26°C (72–79°F)
-
pH: 6.5–7.5 (neutral to slightly alkaline)
-
Hardness: Soft to moderately hard water (5–15 dGH)
-
Water Quality: Maintain pristine water conditions with regular water changes (25–30% 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 3–6 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:
- Provide a separate breeding tank with similar water parameters.
- Include smooth rocks for egg deposition.
- 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.
