For several years hobbyists in the aquarium field were uncertain about the identity of the Andinoacara Rivulatus. The morphs of both the colors, white and gold the “White Saum” or the “Gold Saum” is known as the “GREEN TERROR”.  In fact, these fishes are not the “Green Terror”. The correct identification of the original variety is Andinoacara Stalsbergi, aka “Green Terror”, aka “Silver Saum. These are distinguished as fully developed and bigger in size, the tally of the fins, and the variance in its color. This dilemma took place when the introduction of Andinoacara Stalsergi was stalled in the commercial field, and the Andioacara Rivulatus which is brighter in appearance, drew attention towards itself in the field of recreation, but its species was not identified in the market and was incorporated under those species that included the Green Terror sp, (“Gold Saum”) Aequidens sp. (the “Gold Saum”) for several years in the past. However, no clear demarcation has been received until today.

The gold Saum, scientifically called Andinoaacara Rivulets, synonym, Aequidens Rivulatus belongs to the cichlid group.  This fish is colorful and dwells in the fresh waters.  This fish is indigenous to the Pacific regions of the continent of South America’s coastal regions beginning from the River Tumbes in Peru to Ecuador’s River Esmeraldas.

Growing at home


The ideal method to plan spawning of your Green terror is to bring up a set of young fish which are not related till they mature and grow around 3” and then, permit them to join as pairs. Choose a very sturdy couple to breed, and separate the other couples. This species breeds in classical Aequidens style. They search out an open location in the water and normally spawn on a leveled stone. Other types of cichlids have a tendency of hiding their nests in fissures, whereas the Green terror does not do so. There is no grave restriction of water.  They spawn without difficulty in soft or hard water as well as low or high pH. They demonstrate excellent parenting and spawn normally up to 400.  The female Green terror cichlid plays a leading role to raise the fry.  Raise your fry on fine flake food or baby brine shrimp.

Place your Green terror cichlid in a separate aquarium meant only for it, or else divide the aquarium with the help of a net or glass. In time, the elder Green terror cichlids turn aggressive; hence it is advisable to keep them apart, either dividing the aquarium or by separating one.  The right size of the aquarium depends on the type of species you desire to accommodate with your Green terror cichlid, or provide it with its individual aquarium. For a juvenile Green terror cichlid that has attained a length of 5 inches (13 cm) the aquarium should have as appropriate size is a 132 liter or 35 gallons measuring a minimum of 36 inches (91 cm).  A grown up a Green terror cichlid needs 209 liter or 55 gallon aquarium or bigger and a dimension of minimum 48 inches (122 cm) in length.  For a community aquarium provide a tank no smaller than 379 liter or 100 gallon.

Water Condition

The Green terror cichlid hails from tropical regions of Peru and Ecuador, where the waters are warm; therefore, the temperature of the water in the aquarium needs to be   20 – 24° C (69-75° F). The preference of pH is around 7 (neutral), whereas the Green terror cichlids adjust themselves to bit acidic and alkaline conditions.  Set the pH more than 6.5 and less than 8.0. Avoid intensities and sudden alterations between these levels. The Green terror cichlid’s dH range is 25.

Green Terror Setup

Like very big cichlids hailing from the continent of South America, Green terror fish also  require a lot of area for a single fish. Provide at least 75 gallons as recommended for a couple.  In case you are housing them with other larger fish, a bigger aquarium is required.  The Green terrors perform their best in water that is a bit acidic to neutral and also soft.  Supply competent biological filtration and ensure the movement of the water is low to reasonable.   The Green Terrors need a lot of hiding places such as caves of rocks; they perform well in the normal lighting system in the aquarium.  In order to reduce the pH in case your water is hard, introduce driftwood in the aquarium. Ensure there is open space in the middle for them to swim.   In case you decide to have a big aquarium and house the Green terrors with other varieties.  Then, organize the aquarium and block them from seeing each other, so that the aquarium has divisions of areas in order to suppress their affinity of becoming violent.
