Aequidens Tetramerus

Datasheet

General Description

The Saddle Cichlid, scientifically known as Aequidens tetramerus, belongs to the Cichlidae family under the Perciformes classification order. This cichlid showcases a variety of color forms depending on its locality, with some specimens from Ecuador and Peru highly sought after for their vibrant red or orange lower body coloration, while those from Brazil typically exhibit grey, blue, or green hues. Current taxonomic classification suggests that A. tetramerus may represent a group of related fishes rather than a singular taxon.

Aquarium Setup

When setting up an aquarium for the Saddle Cichlid, it is recommended to incorporate a soft, sandy substrate, although not essential for their well-being. Other favorable tank features include dim lighting, driftwood, scattered roots and branches, and one or two flat rocks for potential spawning sites. Saddle Cichlids are sensitive to poor water quality, necessitating a well-maintained environment with over-filtration through canister filters or a sump system. Regular water changes of 50-70% per week are advised to maintain stable water conditions and promote optimal health.

Behaviour

Male Saddle Cichlids exhibit territorial behavior, particularly during spawning periods, and may prey on very small tank mates. However, they can coexist with other cichlids as long as an adequate amount of space is provided within the aquarium setting.

Feeding and Diet

In the wild, Saddle Cichlids are omnivorous, with invertebrates forming a significant part of their diet. In aquariums, it is recommended to offer high-quality sinking dry foods supplemented with live or frozen options such as bloodworms and Artemia to replicate their natural feeding habits.

Reproduction & Dimorphism

Saddle Cichlids are biparental substrate spawners and are relatively uncomplicated to breed. To encourage breeding, acquiring a group of at least six juvenile specimens and allowing pairs to form within the group is a successful method. Male Saddle Cichlids are larger than females and develop fin extensions as they mature. During the spawning period, males exhibit more vibrant coloration compared to females.

Habitat and Distribution

Naturally inhabiting various locations in South America, particularly in the Amazon system, Saddle Cichlids prefer slow-moving or still waters with well-structured substrates like submerged tree roots and leaf litter. They are commonly found in tributary drainages, floodplain lakes, and oxbows, often favoring areas with dense aquatic plant growth. The species has been observed in regions spanning from northern Brazil to French Guiana, exhibiting adaptability to different water types ranging from black and clear to white.
