Amphilophus citrinellus, commonly known as the Midas Cichlid, is a large and robust freshwater fish native to Central America. It is renowned for its highly variable coloration, ranging from dull grey to vibrant orange, red, or yellow. This species is characterized by a deep, compressed body, a prominent nuchal hump in mature males, and powerful jaws. It is an intelligent and highly territorial fish, often displaying complex behaviors.

Identificatietips
Nuchal Hump
Look for a prominent fatty hump on the forehead, especially in mature males. This feature is less pronounced or absent in females and juveniles.
Coloration
While highly variable, the Midas Cichlid often exhibits bright yellow, orange, or red hues, particularly in captive-bred specimens. Wild forms are typically duller, grey to olive-brown.
Body Shape
Observe the deep, robust, and laterally compressed body. It is a powerful-looking fish.
Lip Structure
Note the thick, fleshy lips, which are characteristic of the species and related Amphilophus cichlids.
Habitat
- Watertype
- freshwater
- Diepte
- Typically found in shallow to moderate depths, often near rocky substrates or submerged vegetation.
- Omgeving
- Native to large, turbid lakes and rivers in Central America, particularly in Nicaragua and Costa Rica. They prefer areas with rocky outcrops, submerged logs, and sandy or muddy bottoms where they can establish territories and forage.
- Geografisch verspreidingsgebied
- Endemic to the Great Lakes of Nicaragua (Lake Managua and Lake Nicaragua) and their associated drainages, as well as some rivers in Costa Rica.
Aquariuminformatie
- Verzorgingsniveau: intermediate
- Temperament: aggressive
- Dieet: omnivore
- Minimale aquariumgrootte: 75 gallons (280 liters) for a single specimen, larger for pairs or community tanks with appropriate tank mates.
- Temperatuur: 75-82°F (24-28°C)
- pH-waarde: 6.5-8.0
- Hardheid: 5-20 dGH
- Compatibiliteit: Best kept alone or with other large, robust, and equally aggressive cichlids. Not suitable for community tanks with smaller or docile fish. Can be kept in pairs if a large enough territory is provided and aggression is managed.
- Speciale vereisten: Requires a spacious aquarium with strong filtration due to its large size and waste production. Provide plenty of hiding spots and territorial markers using rocks, caves, and driftwood. Substrate should be sand or fine gravel as they enjoy digging. Regular water changes are crucial for maintaining water quality.

Belangrijke feiten
Color-Changing Abilitiesbehavior
Midas Cichlids are famous for their ability to change color rapidly, often in response to mood, stress, or breeding condition. This can range from dull to brilliant hues in a matter of minutes.
Nuchal Hump Developmentinteresting
Mature males often develop a prominent fatty nuchal hump on their forehead, which is a secondary sexual characteristic and can be an indicator of dominance and reproductive fitness.
Intelligent and Interactivebehavior
These cichlids are known for their intelligence and can often recognize their owners, respond to their presence, and even be hand-fed, displaying complex behaviors not commonly seen in many fish species.
Ecological Roleinteresting
In their native Central American lakes, Midas Cichlids are important predators and also play a role in bioturbation through their digging activities, which can affect substrate composition and nutrient cycling.
Species Complexevolution
The taxonomy of Amphilophus citrinellus and its close relatives, particularly A. labiatus, has been a subject of considerable debate and research, with some scientists considering them part of a 'species complex' due to high variability and hybridization.
Veiligheidsinformatie
Voorzichtig hanteren- Veiligheidsniveau: caution
- Giftig: Nee
- Eetbaarheid: edible
- Hanteringsnotities: Midas Cichlids are large, powerful fish with strong jaws and teeth. They can inflict painful bites if handled carelessly. When netting or transferring, use a sturdy net and exercise caution to avoid being bitten. Their aggressive nature also means they can be highly territorial and may attack other fish or even human hands if they perceive a threat to their territory or offspring.
Vergelijkbare soorten
Red Devil Cichlid
Amphilophus labiatus
Historically, A. citrinellus and A. labiatus were often confused or considered the same species. A. labiatus typically has much thicker, more exaggerated lips and a more elongated body shape compared to the deeper-bodied A. citrinellus. However, hybridization is common, making visual differentiation challenging in some cases. Genetic analysis is often required for definitive identification.
Flowerhorn Cichlid
Hybrid (various cichlid species)
Flowerhorn cichlids are man-made hybrids, often involving Midas Cichlid genetics. They typically have an even more exaggerated nuchal hump, distinct black markings (flower patterns) on their flanks, and a more rounded body profile than pure A. citrinellus.
Red Terror Cichlid
Cichlasoma festae
While also large and aggressive, Cichlasoma festae has a more elongated body, distinct vertical barring (especially when stressed or young), and a different head shape. Its coloration is typically red-orange with black markings, but the overall body plan is different.
