Andinoacara Rivulatus

Datasheet

General Description

The Andinoacara Rivulatus, commonly known as Gold Saum, is a member of the Cichlidae family and belongs to the Perciformes classification order. They can grow up to 30.0cm in size and are native to the extreme northern regions of Peru and the coastal drainages of western Ecuador. Inhabiting coastal waters such as streams and rivers, this species exhibits unique behaviors and requirements in captivity.

Aquarium Setup

For optimal care of the Gold Saum, a tank size of a minimum of 300 liters is recommended. The tank should feature a soft, sandy substrate, driftwood branches, and large flat rocks to serve as potential spawning sites. Visual barriers within the tank are advised if housing other fish to dissipate aggressive behavior. Floating plants for shade are beneficial; however, rooted plants may not survive well due to the species' digging habits. Maintaining water quality is crucial, requiring efficient biological filtration and a strict maintenance routine.

Behaviour

These cichlids are best kept alone or as a mated pair in sizable tanks of 650 liters or more due to their aggressive and territorial nature. They can coexist with robust cichlids, large Loricariids, big catfish, and active species like silver sharks and tinfoil barbs. Attempting to keep a breeding pair in a community setting often leads to chaos during spawning.

Feeding and Diet

Gold Saum are omnivorous and enjoy a varied diet. A staple of high-quality cichlid sticks supplemented with live or frozen foods such as earthworms, prawns, and mussels is recommended. Including vegetable matter like peas and spinach is essential while avoiding high protein foods like beefheart to prevent digestive issues.

Reproduction & Dimorphism

Reproduction can be achieved by pairing compatible mates, preferably through natural pairing or gradual introduction methods. Females lay eggs, which males fertilize and guard. The fry hatch in a few days and are tended to by the female until they are free-swimming. Males exhibit sexual dimorphism, being larger with prominent nuchal humps and fin extensions, features absent in females.

Habitat and Distribution

Gold Saum predominantly inhabit coastal waters, including streams and rivers. Their natural range extends from extreme northern Peru to the coastal drainages of western Ecuador, possibly reaching the Río Esmereldas drainage and beyond. The species may display variations in form, particularly in regions above the Esmereldas drainage. Water conditions suitable for their habitat include a pH range of 6.5-8.0, hardness of 5-25°dH, and a temperature of 20-24°C.
