Feeding
-
Diet: Provide a varied and balanced diet for optimal health and color enhancement:
- High-quality goldfish pellets or flakes as a staple.
- Live or frozen foods like bloodworms, brine shrimp, and daphnia.
- Include vegetable-based foods such as blanched peas, spinach, or zucchini to prevent swim bladder issues.
Tankmates
- Best housed with other slow-moving fancy goldfish, such as Orandas, Pearlscales, or Lionheads.
- Avoid keeping with fast or aggressive fish, as they may outcompete Ranchus for food or damage their fins.
Breeding
- Breeding Ranchus is possible but requires a separate breeding tank.
- Males will chase females during spawning, and eggs will be scattered on plants or breeding mops.
- Remove parents after spawning to protect the eggs.
- Feed fry with infusoria or finely crushed food until they grow large enough for standard fry foods.
Special Considerations
- Due to their unique body shape, Ranchus are prone to swim bladder issues; avoid overfeeding and provide a fiber-rich diet.
- Regular maintenance and water quality checks are essential for their health.
- Their wen requires care; watch for signs of infections or injuries.
