Midas Cichlid Varieties

Each variety inherits the species defaults above. Only differences are highlighted.

Male (Standard / Adult)

Fully mature males are incredibly heavily built and develop a massive nuchal hump on their heads, especially during breeding. They are highly intolerant of other fish and are best kept as a solitary centerpiece fish.

Differs in 2 traits from base species

Also known as: Show Male, Nuchal Hump, Orange, Barred, White

Adult Size30 cm
TemperamentHighly Aggressive

Female

Females are slightly smaller and generally lack the massive nuchal hump of the males, though they remain intensely territorial. Can sometimes be kept in heavily monitored breeding pairs in very large tanks.

Differs in 3 traits from base species

Also known as: Female Midas

Adult Size25 cm
TemperamentAggressive
StockingNo limit

Juvenile (Grow-out)

Young Midas cichlids often display wild-type grey/barred patterns before 'peeling' into their vibrant adult colors. They grow incredibly fast and will rapidly outgrow small enclosures while becoming increasingly aggressive.

Midas Cichlid Care Guide Summary

The Midas Cichlid, scientifically known as Amphilophus citrinellus, belongs to the Cichlids - Central American family group. Adults reach a maximum size of approximately 30 cm and have a compressed body shape with a fast growth rate. Classified as highly aggressive, this species primarily occupies the mid-level and bottom zones of the aquarium and produces a extreme level of biological waste.

To thrive, the Midas Cichlid requires a freshwater only aquarium with a minimum volume of 280 litres and a tank length of at least 120 cm. Water temperature should be maintained between 23°C and 28°C, with a pH range of 78.5 and a general hardness of 920 dGH. A moderate water flow is preferred.

Due to its specialist needs, the Midas Cichlid is best suited for fishkeepers who can provide a carefully planned setup. This species is available in 3 varieties: Male (Standard / Adult), Female, and Juvenile (Grow-out). Each may differ slightly in size, temperament, or care needs, so it is worth checking the specific requirements of the variety you plan to keep.

Midas Cichlid Habitat Setup

When setting up an aquarium for the Midas Cichlid, a moderate water flow best suits their natural preferences. Because this species occupies the mid-level and bottom zones, the aquarium layout should prioritise open swimming space in the centre of the tank for free movement and sufficient floor space with hiding spots among rocks, wood, or dense planting. Useful additions include a sand substrate to accommodate their sifting behaviour and smooth gravel or rounded substrate to protect their sensitive barbels. Keepers should note that expect substrate disturbance, so lightweight décor should be secured and live planted layouts may be difficult to maintain, as this species tends to uproot or consume vegetation.

Midas Cichlid Compatibility Notes

Classified as highly aggressive, the Midas Cichlid is best housed alone, as they do not tolerate others of their kind in confined spaces. When choosing tankmates, any fish small enough to fit in its mouth will likely be eaten, conspecific aggression can be intense, especially in smaller tanks, and territorial behaviour may cause issues if hiding spots or floor space are limited. Selecting tankmates that favour different water layers from the mid-level and bottom zones can help reduce competition and territorial overlap.

Who Midas Cichlid Is Actually For

Midas Cichlid is best for a fishkeeper who expects a species with attitude and plans the tank around that behavior and can provide someone who understands its individual space requirements. It makes the most sense for a hobbyist who will actually build around its needs, especially sand.

The most common mistake is treating Midas Cichlid like any other community fish and skipping the soft sand it needs to forage safely. Another frequent problem is forcing it into an over-busy community when it would do better with more room or more deliberate tankmate choices.

Cichlids - Central American
35 cm Highly Aggressive

A massive, extremely aggressive Central American cichlid. Aptly named, the Red Devil is highly intelligent, interactive, and famous for 'glass-banging' at their owners. They are powerful diggers that will uproot plants and rearrange decor. Because of their sheer aggression and jaw strength, they are almost exclusively kept as 'wet pets' in solitary setups.

Salvini Cichlid

Trichromis salvini

Cichlids - Central American
22 cm Highly Aggressive

The Salvini Cichlid is a stunning but notoriously aggressive Central American cichlid. In a rare twist for cichlids, females are actually more brightly colored than males, displaying vivid yellow bodies with striking red bellies and contrasting black markings. They are highly territorial ambush predators and will actively hunt smaller fish. Best kept in a large, species-only setup or with similarly robust, heavily armored tank mates.

Redhead Cichlid

Vieja melanura

Cichlids - Central American
35 cm Aggressive

A massive, deep-bodied Central American cichlid famous for its vibrant pastel colors and prominent red head. In the wild, they are primarily herbivorous, but in captivity, they are opportunistic omnivores. They are aggressive, territorial, and possess immense jaw strength, making them capable of destroying most aquatic plants and rearranging tank decor at will.

Black Belt Cichlid

Vieja maculicauda

Cichlids - Central American
30 cm Aggressive

A large, powerful, and strikingly colored Central American cichlid known for the distinctive vertical black band across its midsection and vivid red flushing on its throat and tail.

They cannot be kept in planted tanks.

Trimac Cichlid

Amphilophus trimaculatus

Cichlids - Central American
35 cm Highly Aggressive

The Trimac is a massive, incredibly aggressive Central American cichlid.

A true 'glass-banger', it requires a huge tank, heavy filtration, and is highly intolerant of tank mates. It constantly digs and rearranges decor.

Firemouth Cichlid

Thorichthys meeki

Cichlids - Central American
15 cm Semi-Aggressive

A popular Central American cichlid famous for the bright red coloration on its throat and belly, which it flares to intimidate rivals. They are earth-eaters, constantly sifting sand for food. While territorial, especially during breeding, they are relatively peaceful for a cichlid of their size compared to larger Central American counterparts.
