Cichlids - South American
Reviewed by Guidarium Editorial DeskUpdated May 2, 2026

Commonly sold in the aquarium trade as the 'Green Terror', the Gold Saum (technically Andinoacara rivulatus) is a stunning but highly aggressive Neotropical cichlid. Males develop magnificent iridescent scales, orange/gold-edged fins, and a pronounced nuchal hump. Due to their territorial nature and large adult size, they are best kept as solitary centerpiece fish or with highly robust, similarly-sized tank mates. They are avid diggers and will uproot or destroy most live plants.

Same care requirements as the base species

Also known as: Bull, Male Green Terror, Show Male, Standard

Female (Adult)

Females remain significantly smaller than males, lacking the pronounced hump and extreme trailing finnage. They are slightly less aggressive in a standard setup but will become fiercely aggressive if breeding.

Andinoacara sp. Gold Saum Care Guide Summary

The Andinoacara sp. Gold Saum, scientifically known as Andinoacara sp. "Gold Saum", belongs to the Cichlids - South American family group. Adults reach a maximum size of approximately 25 cm and have a compressed body shape with a moderate growth rate. Classified as aggressive, this species primarily occupies the mid-level and bottom zones of the aquarium and produces a high level of biological waste.

To thrive, the Andinoacara sp. Gold Saum requires a freshwater only aquarium with a minimum volume of 250 litres and a tank length of at least 120 cm. Water temperature should be maintained between 20°C and 25°C, with a pH range of 6.58 and a general hardness of 520 dGH. A moderate water flow is preferred.

Due to its specialist needs, the Andinoacara sp. Gold Saum is best suited for fishkeepers who can provide a carefully planned setup. This species is available in 3 varieties: Male (Adult / Standard), Female (Adult), 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.

Andinoacara sp. Gold Saum Habitat Setup

When setting up an aquarium for the Andinoacara sp. Gold Saum, 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, smooth gravel or rounded substrate to protect their sensitive barbels, and driftwood, which can serve as both a hiding place and a dietary supplement. 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.

Andinoacara sp. Gold Saum Compatibility Notes

Classified as aggressive, the Andinoacara sp. Gold Saum 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 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 Andinoacara sp. Gold Saum Is Actually For

Andinoacara sp. Gold Saum 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 Andinoacara sp. Gold Saum 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.

Fish Similar to Andinoacara sp. Gold Saum

White Saum (Green Terror)

Andinoacara stalsbergi

Cichlids - South American
20 cm Aggressive

Often sold interchangeably under the name 'Green Terror', Andinoacara stalsbergi (the White Saum) is a highly aggressive and territorial South American cichlid. It differs from the true Green Terror (A. rivulatus / Gold Saum) by having striking white edging on its fins rather than orange. They require large tanks, excellent filtration, and are best kept singly or with other robust, similar-sized fish that can hold their own.

Green Terror

Andinoacara rivulatus

Cichlids - South American
25 cm Aggressive

A large, incredibly colorful, and highly aggressive South American cichlid. Known for their striking metallic green/blue scales and vibrant orange or white tail margins. As their name suggests, they are highly territorial and require very careful tankmate selection, usually only coexisting with other large, robust cichlids or armored catfish in very large tanks.

Ocellatus Gold

Lamprologus ocellatus

Cichlids - African
6 cm Aggressive

The Lamprologus ocellatus 'Gold' is a popular and highly charismatic shell-dwelling cichlid endemic to Lake Tanganyika. Despite their tiny size, they are notoriously fierce and will aggressively defend their territory (usually an escargot shell) against much larger fish and even the aquarist's hand. They require hard, alkaline water, fine sand for digging, and an abundance of empty shells.

Red Terror (Festa's Cichlid)

Mesoheros festae

Cichlids - South American
40 cm Highly Aggressive

A massive, apex-predator South American cichlid. Known as the 'Red Terror' due to its absolute intolerance of tank mates and extreme territorial aggression. They are powerful 'glass-bangers' that will uproot plants, rearrange decor, and kill fish of similar or even larger size. Best kept completely alone or as a strictly bonded pair in a massive aquarium.

Gold Barb

Barbodes semifasciolatus

Cyprinids
7.5 cm Peaceful

A highly active, peaceful schooling fish. The common 'Gold' variant is a captive-bred color morph (Schuberti) of the wild Green Barb. They are remarkably hardy and prefer slightly cooler sub-tropical water, making them excellent candidates for unheated indoor aquariums.

White Cichlid

Vieja argentea

Cichlids - Central American
30 cm Aggressive

A striking, large Central American cichlid known for its brilliant silvery-white body speckled with black markings. Currently reclassified by many as Maskaheros argenteus, they are powerful, highly territorial fish. As herbivores/omnivores, they are notorious for shredding live plants and rearranging the tank substrate.
