General Information

The Ram Cichlid (Mikrogeophagus ramirezi) is a stunning, peaceful dwarf cichlid native to the Orinoco River basins in South America. Known for their vibrant colors, both males and females display remarkable color patterns, unlike many other species where males are significantly more colorful. Ram Cichlids prefer calm, slow-moving water, which should be recreated in the aquarium to help them feel secure. Adding blackwater extract to the tank can create a naturalistic habitat and often encourages spawning when both sexes are present.

Though generally peaceful, Ram Cichlids may become mildly territorial when breeding. They are excellent tank mates for other calm, docile fish and thrive in planted tanks with good water quality. Due to their gentle nature, they are ideal for South American-themed community tanks and are known to be curious fish that may approach the glass to interact with their keepers.

Feeding the Ram Cichlid

A varied diet is essential for the health and vibrancy of Ram Cichlids. Provide a balanced diet of high-quality flakes or small cichlid pellets, supplemented with meaty foods such as live or frozen bloodworms, brine shrimp, and daphnia. Their diet should include protein-rich foods to support their energy levels and enhance their coloration. Feed small portions twice daily, ensuring all food is consumed within a few minutes to maintain water quality.

Sexing the Ram Cichlid

Sexing Ram Cichlids can be observed through slight physical differences. Males are often more colorful than females and have a slimmer, more streamlined body. Mature males also develop extended rays on the front edge of their dorsal fins. Females, particularly when preparing to spawn, show a pinkish hue on their belly, which becomes more prominent when they are ready to breed.

Breeding the Ram Cichlid

Ram Cichlids are relatively easy to breed in captivity, particularly when they have access to flat surfaces for spawning. Flat rocks or slate are preferred, but if unavailable, they may dig small pits in the substrate as nest sites. A soft, fine sand substrate is ideal, as it’s gentle on their delicate mouths and allows for natural foraging behavior. Both parents take an active role in protecting the nest, often seen fanning water over the eggs to increase oxygen levels. After a few days, the eggs will hatch, but the fry do not require food until they are free-swimming, usually 4-5 days post-hatching. For breeding success, consider sourcing wild-caught Rams, as captive-bred varieties may have lower fertility rates.

Questions and Answers

On March 25th, 2011, the following answers were moved here from aqua-fish.net/answers due to merging related content.

  • Why do Ram Cichlids need to be kept in pairs?

    Answer: Ram Cichlids are naturally shy fish. Keeping them in pairs helps them feel more secure and confident. Ideally, the pair should consist of a male and female; keeping two males may lead to territorial disputes.

  • What size tank does a pair of Rams need?

    Answer: Ram Cichlids should be kept in pairs, and a tank of at least 20 gallons (~75 liters) is recommended for two fish to ensure they have ample space and comfortable water quality.

Tank Requirements

For a pair of Ram Cichlids, a minimum tank size of 20 gallons (~75 liters) is recommended. They thrive in well-planted tanks with calm waters and require stable water parameters, especially since they are sensitive to water quality fluctuations. Ideal water conditions include a temperature range of 23-30°C (73.4-86°F), a pH between 5 and 7, and soft to moderately hard water. Adding driftwood, Indian almond leaves, or other tannin-producing materials can create natural tannins in the water, mimicking their native blackwater habitat.

Since Rams are sensitive to poor water quality, maintain regular weekly water changes of 20-30% and avoid introducing aggressive or overly active tankmates, which could stress them. A soft, sandy substrate is recommended for substrate-digging and sifting behaviors, while shaded areas created by floating plants or dense vegetation help them feel more secure. Additionally, regular filter maintenance and weekly water testing are advised to keep water parameters stable.

Ram Cichlids are peaceful and compatible with other calm, similarly sized fish. Ideal tankmates include:

Avoid keeping them with large, boisterous fish or fin-nipping species, as Rams are sensitive and may become stressed. Shrimp, such as Amano shrimp, and peaceful snails like Nerites can also make suitable tankmates, adding variety and helping maintain a clean tank.

Plants add natural cover and enhance the blackwater aesthetic favored by Ram Cichlids. Suitable plant choices include:

These plants thrive in lower light levels and help create shaded areas, which reduce stress for Ram Cichlids. Additionally, live plants contribute to water quality by absorbing nitrates and enhancing oxygen levels in the tank.

Short Description

The Ram Cichlid (Mikrogeophagus ramirezi) is a peaceful, vibrant species popular in aquariums for its striking colors and gentle nature. Native to South America’s Orinoco River basins, they prefer calm waters and a well-planted environment. Ideal for community tanks, they pair well with other peaceful fish and require stable water conditions for optimal health. Ram Cichlids may show territorial behavior during breeding but are otherwise friendly and thrive in pairs or small groups.
