Yellow Acara - Aequidens metae : Complete Fish Profile & Care Guide

Introduction

Renowned for their distinctive appearance and engaging behavioural traits, Yellow Acaras (Aequidens metae) hold a place of prominence within the realm of cichlid enthusiasts. This cichlid species, scientifically categorized within the Aequidens genus, captivates with its striking colouration, intriguing social dynamics, and versatile compatibility within diverse aquatic communities. 

Yellow Acaras, characterized by a moderate level of aggression, emerge as judicious selections for cichlid communities of larger proportions. Their compatibility extends to counterparts such as Severum and Chocolate Cichlids, while the presence of sizeable Tetras and Silver Dollars serves to imbue a sense of tranquillity within the wary cichlid populace. Avoid keeping these Cichlids with smaller fish as they may well be bullied, and very small fish will be eaten.

Akin to their wild behaviour, these fish tend to adopt loose aggregations outside of their breeding periods. Maintaining them in a small collective grouping not only fosters engagement among individuals but also facilitates the natural pairing process during the spawning phase, resulting in harmoniously aligned partnerships.

The proper establishment for accommodating Yellow Acaras demands a biologically mature and expansively spacious aquarium. Efficient filtration mechanisms, proficiently delivering moderate water movement, stand as essential components to sustain optimal aquatic conditions. Ensuring the integration of abundant concealment options is pivotal, with a deliberate arrangement of intertwining driftwood formations, rocky alcoves, and substantial vegetation serving as ideal retreats.

Sustaining the health of this species warrants a regimen of regular partial water changes, instrumental in maintaining minimal nitrate levels. This practice assumes heightened significance, given the Yellow Acaras' vulnerability to fluctuations in water quality. 

Yellow Acaras can be readily identified through the presence of two prominent markings. Positioned strategically, one is situated approximately mid-flank, while the other adorns the base of the caudal fin. The mid-flank marking often exhibits a noteworthy encirclement of yellow, harmonizing with the underlying hue of yellowish-green with quite large scales. The scales are grey with black borders, which reflect light nicely. Noteworthy among their distinguishing features is a distinctive dark brown vertical stripe framed in turquoise, which originates from the eye and descends along the anterior periphery of the operculum.

During the phases of spawning and brood care, Yellow Acaras exhibit a striking and conspicuous divergence in their colouration. This transformation is characterized by a notable luminescent yellow-orange hue encompassing the eye region, while the remaining sections of the body, notably the opercula, chest, and throat, assume a distinctively darker shade.
