Myloplus Rubripinnis

Datasheet

General Description

The Redhook, scientifically known as Myloplus Rubripinnis, is a species often mistaken for Silver Dollars due to its similarities but can be differentiated by its prominent black-trimmed red anal fin. Growing larger than typical Silver Dollars, this species is also referred to as Myleus Rubripinnis. It is considered a challenging species to care for but can thrive in suitable conditions.

Aquarium Setup

In the wild, the Redhook inhabits densely planted river tributaries, but in captivity, replicating this environment can be challenging as the species is known to consume plants. Opt for hardy plants that may need regular replacement or consider using artificial plants. To boost the fish's confidence, provide dim lighting and areas of refuge. The recommended tank size is a minimum of 265 liters, with water conditions of pH 6.0-7.0, hardness of 0-10 dH, and a temperature range of 23-27°C.

Behaviour

Redhooks are social fish best kept in groups of at least five individuals. They are generally peaceful community fish, compatible with larger non-aggressive species. However, smaller fish may be viewed as food. These fish tend to occupy the middle and top areas of the aquarium, so selecting tankmates that utilize the bottom space can add variety. Peaceful catfish like plecos and doradids make suitable companions.

Feeding and Diet

As herbivores, Redhooks primarily feed on submerged or marginal vegetation in their natural habitat. To replicate this diet in captivity, provide a variety of vegetable matter such as courgette, cucumber, peas, and green vegetables. Commercial foods like algae wafers, spirulina, and vegetable flakes are also recommended. Additionally, Redhooks readily accept most aquarium foods and enjoy treats like bloodworms and brine shrimp.

Reproduction & Dimorphism

Reproduction of Redhooks has not been achieved in aquarium settings, and sexual dimorphism is not distinctly known. However, males may exhibit a slightly longer anal fin compared to females.

Habitat and Distribution

The Redhook is native to various regions in northern South America, including Ecuador, Venezuela, Colombia, Guyana, and Brazil. It inhabits slow-moving sections of rivers, particularly where there is dense growth of marginal or overhanging vegetation. Major river systems like the Amazon and Rio Orinoco are part of its distribution area.
