🌡️ Water Parameters:
| Parameter | Ideal Range |
|---|---|

| GH (Hardness) | 5 – 19 dGH |
| Ammonia/Nitrite | 0 ppm (very sensitive) |
| Water Type | Freshwater only (do not tolerate salt for long periods) |
💧 Ranchus need clean, stable, and oxygen-rich water. Avoid sudden pH/temp changes.
🏡 Tank Setup:
| Feature | Recommendation |
|---|---|
| Tank Size | Minimum 30 gallons for one Ranchu; +10 gallons per additional fish |
| Substrate | Sand or bare-bottom (for easier cleaning) |
| Decor | Smooth rocks, live plants like Anubias, Java Fern (avoid sharp or rough items) |
| Filter | Strong filtration but gentle flow (use sponge filter or pre-filter sponge) |
| Heater | Recommended for stable tropical temps |
| Aeration | Use air stones to ensure good oxygen exchange |
⚠️ Avoid fast currents — Ranchus are slow swimmers and may struggle.
🍽️ Feeding Guide:
| Type | Examples |
|---|---|
| Staple Diet | High-quality sinking goldfish pellets or gel food |
| Supplemental | Bloodworms, daphnia, brine shrimp (live or frozen) |
| Vegetables | Blanched peas (shelled), spinach, zucchini |
| Feeding Tips | Feed small amounts 2–3 times daily; avoid floating food to prevent gulping air |
✅ Soak pellets to soften them. Feed sinking food to reduce swim bladder issues.
🧼 Maintenance Tips:
-
Perform 30–40% water changes weekly
-
Use a gravel vacuum to remove waste
-
Test water regularly for ammonia/nitrite/nitrate
-
Ranchus produce a lot of waste, so overfiltration is helpful
