Are you considering adding a jewelfish, also known as a ruby cichlid, to your aquarium? These vibrant, hardy fish are a favorite among aquarists, but they do come with unique care requirements. If you're looking for reliable, vet-reviewed advice on how to care for these colorful fish, you're in the right place. Let’s dive into everything you need to know about keeping jewelfish happy and healthy.

🩺 Vet Recommendations

Jewelfish (Hemichromis bimaculatus) are native to West Africa, where they thrive in freshwater rivers and streams. As a popular choice in aquariums, they’re known for their striking red coloration and bold personalities. However, their care requires proper planning to ensure they stay healthy and stress-free.

Here are some key points to consider when caring for jewelfish:

  • Tank Size: Jewelfish need plenty of space. A minimum of 30 gallons is recommended for a single pair, with larger tanks required for community setups.
  • Water Parameters: They prefer warm water (75–82°F) with a pH range of 6.5–7.5. Consistent water quality is critical, so invest in a reliable filter and test water parameters regularly.
  • Diet: These fish are omnivores and require a varied diet. High-quality pellets, frozen or live foods (like brine shrimp and bloodworms), and occasional vegetable matter will keep them healthy.
  • Temperament: Jewelfish are territorial and can be aggressive, especially during breeding. Plan tankmates carefully to avoid stress and conflict.

With the right environment and care, jewelfish can live up to 5–7 years, making them a rewarding addition to your home aquarium.

📋 Care Tips

Caring for jewelfish can be straightforward if you understand their needs. Here are some practical tips to ensure their well-being:

  • Aquascaping: Include rocks, caves, and driftwood to mimic their natural habitat and provide hiding spots. Avoid sharp decorations that could injure them.
  • Filtration: Choose a filter that can handle the bio-load of an active fish like the jewelfish. They thrive in clean, well-oxygenated water.
  • Feeding Routine: Feed them small portions 1–2 times daily, ensuring they eat within a few minutes to avoid overfeeding and water contamination.
  • Breeding Considerations: If you plan to breed jewelfish, provide a separate breeding tank. These fish are attentive parents but can become very aggressive during spawning.

Pay attention to their behavior and health. Early intervention is key if you notice any signs of stress, illness, or aggression.

✅ Do’s and Don’ts

To help you avoid common mistakes, here’s a quick guide on what to do and what to avoid when keeping jewelfish:

  • Do: Perform weekly water changes (20–30%) to maintain water quality.
  • Do: Research tankmates thoroughly. Compatible species include larger, non-aggressive fish like plecos or certain barbs.
  • Do: Observe your fish regularly for changes in behavior or appearance.
  • Don’t: Overcrowd the tank. Jewelfish need space to establish territories and reduce stress.
  • Don’t: Mix them with small or timid fish, as they may be bullied or injured.
  • Don’t: Ignore water testing. Poor water quality is a leading cause of health issues in aquariums.

By following these guidelines, you’ll create a safe and enriching environment for your jewelfish to thrive.

💡 Expert Advice

Jewelfish are a wonderful choice for aquarists who appreciate their beauty and unique personality. However, they’re not ideal for beginners due to their territorial behavior and specific care needs. If you’re new to fishkeeping, consider starting with a more community-friendly species before transitioning to jewelfish.

It’s also important to have a plan in place for managing aggression, especially if you’re introducing new tankmates or breeding. Monitoring their behavior and maintaining optimal water conditions can go a long way in preventing problems.

If you’re ever unsure about your jewelfish’s health or behavior, consulting with a vet experienced in aquatic animals is a smart move. Early advice can save you time, money, and stress in the long run.

FAQs

Q: Can jewelfish live with other cichlids?
A: While some aquarists successfully keep jewelfish with other cichlids, it depends on the species and tank size. Provide plenty of space and hiding spots to minimize territorial disputes.

Q: Why is my jewelfish hiding all the time?
A: Hiding can indicate stress, illness, or an unsuitable tank setup. Check water parameters, ensure they have enough hiding places, and observe for signs of bullying or disease.

Q: How can I tell if my jewelfish is healthy?
A: Healthy jewelfish are active, have vibrant coloration, and show interest in food. Watch for signs of illness like lethargy, clamped fins, or unusual spots on their body.
