Aquarium information

Aquarium description

Set-up date

January, 2025

Aquarium decoration

The aquarium was designed to replicate a slow-flowing Bolivian lowland stream habitat. A natural sandy substrate was selected to reflect the soft riverbeds where Bolivian Rams forage, combined with driftwood structures that provide shelter, territorial boundaries, and a natural appearance.

Leaf litter and accumulated organic matter were allowed to develop, mimicking the nutrient-rich substrates found in natural habitats. Surface cover from floating vegetation provides shade and contributes to a more natural environment.

The aquascape focuses on open sandy areas, wood structures, and a calm riverine appearance rather than a heavily planted aquarium, reflecting the natural habitats of Mikrogeophagus altispinosus.

Aquarium equipment

The aquarium is equipped with a SunSun HW-302 external canister filter, providing mechanical and biological filtration while maintaining gentle water movement suitable for a slow-flowing river biotope. The filtration system supports stable water quality and adequate oxygenation.

Temperature and water parameters are monitored regularly to maintain suitable conditions for Bolivian Rams (Mikrogeophagus altispinosus).

Fish care

The Bolivian Rams (Mikrogeophagus altispinosus) are maintained in a group to encourage natural social behaviour and reduce stress. They are provided with a varied diet, primarily consisting of Tetra Bits, a high-quality granulated food suitable for cichlids.

Feeding is carried out in controlled portions to minimise excess waste and maintain good water quality. The fish are observed regularly for health, behaviour, and natural interactions. Stable water parameters, gentle filtration, open sandy areas for foraging, and driftwood shelters help replicate their natural environment and support their wellbeing.

Fish:

• Mikrogeophagus altispinosus (Cichlidae) – Bolivian Ram – 6

Plant care

No submerged aquatic plants are maintained in this aquarium. The biotope design focuses on natural hardscape elements such as sand, driftwood, leaf litter, and open swimming areas. Floating vegetation is allowed to grow naturally without additional fertilisation or CO₂ supplementation.

Water care

Water maintenance consists of regular partial water changes to maintain stable water quality and replicate the clean, slow-moving waters of Bolivian river habitats. Water parameters are monitored periodically, with attention to pH, hardness, temperature, and dissolved oxygen levels.

Organic debris and leaf litter are allowed to accumulate naturally, while excess waste is removed during routine maintenance.
