OB Peacock Cichlid Tank Setup

Setting up a tank for your OB Peacock Cichlid isn’t as daunting as it may seem. The first thing to know is your fish will need ample space. A minimum tank size of 55 gallons (208 liters) is required. This gives them the room they need to swim and establish territories.

Moving onto the substrate, a sandy bottom is best. It replicates their natural habitats and allows them to exhibit their normal digging behavior. You may also want to include:

  • Rocks: These fish love rocks and cave-like structures. They not only provide shelter but also help in creating territories.
  • Plants: Though not essential, they can enhance the aesthetics of the tank. Ensure they are sturdy and firmly rooted.

Equally important is the setup of your water filter. A robust water filtering system is crucial to their health. Remember, these fish are used to clear, clean water. Ensure the filter is powerful enough for the tank’s capacity.

As for lighting, OB Peacock Cichlids don’t have specific requirements. Standard aquarium lighting will suffice. However, keep in mind that excessive light can cause algae growth.

In addition, consider the tank’s location. It should be in a spot free from direct sunlight and sudden temperature swings.

OB Peacock Cichlid Water Requirements

The ideal water condition is fundamental to the longevity and vitality of your OB Peacock Cichlid. The optimum water temperature should range between 75°-82°F (24°-28°C). To monitor these levels, consider investing in a reliable aquarium thermometer.

  • Maintaining an ideal water temperature is pivotal. This encourages normal physiological functions and prevents the fish from stress-related illness.

The species prefer water with a pH range of 7.5 to 8.5, indicating a preference for slightly alkaline conditions. You can use a pH testing kit to ensure your aquarium water stays within this range.

  • Regular water changes are mandatory. Aim for a 25% water change every week. This helps not only to maintain ideal water properties but also to reduce toxins.

The OB Peacock Cichlid thrives in a minimum tank size of 55 gallons, thus giving them plenty of swimming space. More spacious tanks will enhance the well-being of these active species.

OB Peacock Cichlid Diet and Feeding

An integral aspect of OB Peacock Cichlid care is feeding. The diet of these fish is omnivorous, which means they’ll eat both plant-based and meat-based food.

  • You can feed them a mixture of commercially prepared fish food, such as flakes or pellets, combined with occasional servings of live or frozen food like brine shrimp or bloodworms.
  • In terms of frequency, feeding your OB Peacock Cichlid twice a day in small portions is ideal.

Remember, overfeeding can make the aquarium water dirty and cause health problems for your fish.

It is also advisable to monitor them during feeding times. Not only to ensure they are eating properly but also to catch any signs of illness early. If a fish refuses to eat, it can be a sign of stress or disease.

A balanced diet, feeding the right quantity, and timely observation are the essential tactics for a healthy OB Peacock Cichlid feeding routine. Providing a spectrum of nutrients will not only keep your OB Peacock Cichlid healthy but also highlight their vibrant colors. Make their meal times enriching with a variety of treats that fit their diet type.

OB Peacock Cichlid Care Schedule

Your OB Peacock Cichlid requires diligent and consistent care to thrive. Understanding and following a structured care schedule is indispensable.


Feed your Cichlid twice daily with a diet of protein and vegetable matter. Monitor the water temperature closely, it should remain steady between 75°-82°F (24°-28°C).

Observing your Cichlid daily can provide clues to potential health issues; lethargic or unusual behavior is often an early sign of disease.


The water quality of your tank must be checked once a week. Ensure the pH is kept between 7.8 and 8.6 and the water hardness between 10-20 dGH.


Here’s a condensed to-do list for your monthly care schedule:

  • Perform a partial water change of 10%-20% to maintain water cleanliness
  • Inspect your tank’s filter and clean or change it as needed
  • Check the tank and equipment for any damage


A comprehensive health check by a veterinarian experienced with fish is beneficial. Just like other pets, potential problems can be prevented with routine vet visits.

Don’t forget that no care schedule will ever replace careful observation. No two tanks, no two fish are exactly alike. Trust your instincts and never ignore abrupt changes in behavior, color, and feeding habits. They’re typically your first sign something might be off.

OB Peacock Cichlid Health Problems

In your quest to create a thriving environment for your OB Peacock Cichlid, it’s crucial to anticipate potential health issues. Just like any other pet, these fish can suffer from various diseases. However, most health problems can be prevented or mitigated with proper tank maintenance and nutrition.

Common Diseases: The dominant health threats include Ich, also known as White Spot Disease, and Malawi Bloat. Ich manifests as white spots on the fish’s body, while Malawi Bloat is indicated by a swollen abdomen, loss of appetite, and unusual swimming behavior.

Prevention: Regular water changes and monitoring your fish for abnormal signs can significantly help in disease prevention. Darkened colors, loss of appetite, and a sudden change in behavior can serve as early indicators of potential health issues.

Treatment: Should your OB Peacock become ill, there are varying treatments available. Ich can be treated with over-the-counter medication and raising the tank temperature. Malawi Bloat should be dealt with immediately by isolating the affected fish, feeding them peas, and consulting with a vet.

Remember, early detection is imperative to managing and overcoming these problems. Keep a vigilant eye on your tank inhabitants to ensure they remain vigorous and disease-free.

OB Peacock Cichlid Tank Mates

When planning a community tank, the choice of tank mates for your OB Peacock Cichlid is critical. Remember, this species is extremely active, and occupies the mid to bottom part of the tank.

One proven strategy is to keep them with other Malawi Cichlids. For instance, Mbuna Cichlids, being equally active and dramatic in color, make lively counterparts. Other Peacock Cichlids of the Aulonocara genus also get along well with them, allowing for an attractive mix of colors in your tank.

Here is a list of potential OB Peacock Cichlid tank mates:

  • Mbuna Cichlids
  • Other Peacock Cichlids
  • Synodontis Catfish
  • Pleco

While the above list provides some safe teammates, avoid slow-moving or overly-aggressive fish. The activity levels and territorial nature of OB Peacock Cichlids tend to agitate them.

Conclusively, while the OB Peacock Cichlid exhibits compatibility with similarly active and non-aggressive Cichlids, always keep an eye on the tank dynamics. Irrespective of whether you choose one type or a mix of the suggested tank mates, ensure that your tank’s size supports the fish population.

OB Peacock Cichlid Breeding

Breeding OB Peacock Cichlids isn’t a complicated process, but there are some key aspects you must be aware of.

Male and Female Ratio: Firstly, maintain a ratio of two females for every male in your tank if you wish to breed. An all-male tank will not work for breeding purposes. Balancing out the male-female ratio will reduce aggression, and your females will not be overly stressed.

Spawning: OB Peacock Cichlids are mouthbrooders, meaning the female holds the eggs in her mouth for incubation. Post mating, the female picks up the eggs and incubates them in her mouth for about 21-28 days.

Stable Environment: During this period, it’s crucial to provide a stable tank environment. Any sudden changes in temperature or water conditions can stress the mother, leading to the premature dropping of eggs.

Post Care: Post hatching, the female continues to protect the juveniles in her mouth for a few more days. At this point, it’s advisable to offer a diet rich in protein to aid in fry’s development.

OB Peacock Cichlid breeding requires a balanced gender ratio, a stable environment, and appropriate post-care. By adhering to these guidelines, you’ll find breeding these vibrant fishes a rewarding experience.


Keeping an OB Peacock Cichlid can be a rewarding experience, especially for fish enthusiasts who appreciate lively and colorful aquarium inhabitants.
