Keyhole cichlid, also known as cleithracara maronii, gets its name from the ebony keyhole-shaped stripe on its body.
Because of their benthic nature, they are a rather solitary yet serene fish species. However, they have since evolved, and you can breed them in community aquariums.
This article would talk about your keyhole cichlid’s total care system, ranging from feeding it to imitating its natural habitat.

Keyhole Cichlid Care
There three other aspects to look at when caring for a keyhole cichlid; PH levels, temperature, and habitat.
1. PH level
They can survive in water habitats with a very low PH, but you should maintain a PH of 6.8-8.0. Ensure to use a filter for their fish tank to reduce and maintain the standard nitrate levels. Cleaning the tank is necessary because it helps conserve water quality and prevents your keyhole cichlid from diseases.
For a keyhole cichlid tank’s temperature, its range should be (75 to 81) Fahrenheit or (25-27) degrees Celsius. It can be a challenge if you reside in any of the cold temperature regions. However, a heater would suffice; get one to regulate and monitor, so the conditions are not extreme.
The keyhole cichlid is extraordinarily timid and depends on its habitat to mask or hide it when it feels threatened. It does not mean you should cover the entire tank with caves and rocks. Strike a balance and leave some space for it to swim and play around.
You have to artificially simulate its natural habitat by adding rocks and plants or cave-like shelters. While you decorate their habitat, create a false division in the tank because they like their space and are territorial. In the case of spawning, the keyhole cichlid prefers flat-shaped rocks, so you have to add some into the tank if you except a fry.
Keyhole Cichlid Tank Mates: Accommodating other species
The keyhole cichlid compatibility with other species is satisfactory. They are accommodating and can live peacefully with other fishes, so they are ideal for a community aquarium. However, the keyhole cichlids tank mates should be fish of similar nature. They need to be gentle, of similar size and require the same water conditions (temperature, ph. and territorial divisions).
It is most likely to prey on smaller aquatic animals like crustaceans or tetras. So keep that in mind when building a school in your aquarium. The keyhole cichlid’s monogamous nature causes it to pair up with another of its kind of its choosing. They are always frightened and feel defensive but cope with others when they can hide easily.
Its extreme aggression is off the charts during spawning as they are to safeguard their young. However, they return to their peaceful nature when the other fish move away from their shelter.
Keyhole Cichlid Breeding: Behavior and Breeding Conditions
– Keyhole Cichlids Breeding Behavior
As with other parents, the keyhole cichlid is instinctively protective of their young but aggressive towards any suspected predator. It can live peacefully as a monogamous species even after the spawning periods. You do not need to simulate them to mate as they would naturally produce fry if the tank has both sexes.
– Breeding Conditions
In an artificial habitat, the keyhole cichlids require a standard water temperature, PH, shelter, and flat surface to breed. Flat concrete surfaces (such as a stone or leaves) are critical, as they would only release eggs when they feel safe and secure. The eggs hatch into fry in less than a week and start actively swimming around their territory within a short time.
You can give your baby keyhole artemia nauplii (brine shrimps) at this time. Even when the habitat is comfortable, some fry will not make it significantly if the amount of fish present surpasses the water level or tank size. However, if you can separate the keyhole cichlid into a different conducive tank, it will increase the fry survival rates.
– Protective Instincts
Female cichlids will lay up to 300 eggs at a time and take turns with their mates to watch after them for weeks. They can protect their fry for up to half a year, with the female guarding directly around the egg, the male around their shelter. Both keyhole cichlids would employ the use of oxygenated water to sift through the eggs. They detect and separate the unfertilized ones to prevent infections.
Parent instincts are sadly not common amongst younger keyhole cichlid as they would often feed on their young. Nonetheless, they do this only when they feel threatened. Larger fish or predators are the usual culprits, but the cichlid would rather eat the eggs themselves than allow others.
Keyhole Cichlid Diseases: What It’s Most Likely To Suffer From?
Let’s talk about them.
1. The Ichthyophthirius Multifiliis Pathogen
It is a ciliate that seeps through the keyhole cichlids skin and can survive eight weeks under the right temperature.
At around 1mm in size, they detach themselves from the cichlid and swim off. The pathogen continues to grow and multiply until it needs to reattach itself to a host. It is highly contagious and will spread fast to other inhabitants of the tank.
Signs Of The Ichthyophthirius Multifiliis In A Keyhole Cichlid
- Whitish spots all over their body, including gills and fin and weight loss
- They seem itchy and frequently rub their body against shelters and rocks.
- Problems with breathing and their fins are squeezed shut.
An appropriate dose of malachite green and formaldehyde is the perfect cure against the ichthyophthirius multifiliis. Also, you can use methylene blue to treat mild cases of this disease. However, act fast as soon as you notice because ichthyophthirius multifiliis causes kidney issues or fatality. Run the medication via the water filter and into the tank for a thorough treatment method.
2. Surplus Flagellates In Keyhole Cichlid
They are micro-organisms that thrive in the keyhole cichlid intestine but only cause issues when they multiple excessively. The spread of the flagellates is due to illness, dietary deficiency, and wrong water conditions.
Signs Of Surplus Flagellate In A Keyhole Cichlids
• Change in color
• Loss in appetite
• White threadlike dropping
A sufficient dose of ”metronidazole” is an excellent remedy to get rid of the surplus flagellates. It is active against the reproduction of anaerobes. Diagnose the root disease that led to the multiplication of flagellate in the cichlid intestine and tackles it.
3. Fin Rot In Keyhole Cichlids
As the name implies, it is a case where the fins of the keyhole cichlid begin to rot due to a bacterial infection. The primary cause of this disease is incorrect water conditions such as dirty water or wrong ph level. However, under the right situations, the keyhole cichlids can still get this because it is stressed. We know this species is timid and would instead be left alone. So if other fishes in the aquarium keep coming close, it causes them to live in fear.
Signs Of Fin Rot In Keyhole Cichlids
- The fin begins to look milky transparent.
- The keyhole cichlids behave weak and slow.
- The fins become weak and dissipate gradually.
- Mold begins to cover the fin and expedite the rot.
To treat fin rot on a cichlid:
- quarantine the fish
- Increase the water temperature of the new tank and add a bit of salt into the water.
- Use antibiotics or anti-bacteria medications
Most keyhole cichlids suffering from fin rot predominantly die from stronger predators. As other inhabitants observe and notice a weaker or sluggish fish, they chase it down and finally attack it until it dies.
Keyhole Cichlids Diet: Meals to Give
The keyhole cichlids diet include frozen food, vegetables and flesh like crustaceans and worm. We also suggest meat or veggie-based pellets are also ideal. You can feed younger keyhole cichlids with brine shrimps and worms. They are highly nutritious and help them mature rapidly.
Frequency And Size
You can opt for smaller multiple feeding schedules or feed them two main meal times. Change up the food, so it doesn’t get boring, and cut them into fish-bite-sized pieces.
- The keyhole cichlids are a timid species yet compatible with other fishes.
- They stick with one partner even after breeding.
- They lay their eggs on flat concrete surfaces.
- They aggressively protect their young against predators.
- They can live up to 10 years.
- They eat both vegetables and fleshy foods.
Keyhole cichlids are an adaptable but solitary breed. Under the right habitat conditions, they thrive without extra effort. How about you get a pair of keyhole cichlids and enjoy life with this exciting species.
