Vieja Zonata

Datasheet

General Description

The Oaxaca Cichlid, scientifically known as Vieja Zonata, is a hardy and moderately aggressive cichlid species. It is primarily herbivorous, making vegetable matter like spirulina and algae wafers essential in its diet. While rarely found in aquatic stores, it can be obtained through specialist cichlid dealers. Males of this species are larger, more colorful, and display dorsal and anal fin extensions, as well as a nuchal hump.

Aquarium Setup

For Oaxaca Cichlids, a minimum tank size of 500 liters is recommended. Tank setup is flexible as the fish will rearrange decor according to its preference. Utilizing rocks, bogwood, and branches is advised, ensuring their secure placement to prevent damage to the aquarium glass. A substrate of sand or fine gravel is suitable, and lighting levels are not critical. Proper filtration to maintain water quality is essential for this species.

Behaviour

When provided with ample space and territorial features, Oaxaca Cichlids can be kept in groups with similar-sized cichlids and robust species. It is recommended to introduce all fish as juveniles and allow them to grow together to increase success rates. However, this species may consume fish small enough to fit in its mouth, so caution is needed when selecting tankmates.

Feeding and Diet

The Oaxaca Cichlid is primarily herbivorous, necessitating a diet consisting of vegetable matter like spirulina and algae wafers. Additionally, they accept cichlid pellets, live foods such as bloodworms and brine shrimp, and meaty treats like prawns and mussels. Providing a varied diet is crucial for their overall health and nutrition.

Reproduction & Dimorphism

Breeding Oaxaca Cichlids can be challenging due to potential aggression between the pair. However, once a breeding pair is established, spawning typically occurs with proper preparation of a spawning site. The male may exhibit aggression towards the female during spawning, but this behavior is normal. Males are larger, more colorful, and develop fins extensions and a nuchal hump compared to females.

Habitat and Distribution

Native to the River Tehuantepec drainage in eastern Mexico, the Oaxaca Cichlid is endemic to this region. Their natural habitat consists of freshwater rivers with moderate water hardness ranging from 0-20°dH, a pH level of 7.0-7.5, and temperatures between 23-30°C.
