Bolivian Ram

The Bolivian Ram, scientifically known as Mikrogeophagus altispinosus, belongs to the Cichlids - South American family group. Adults reach a maximum size of approximately 8 cm and have a compressed body shape with a moderate growth rate. Classified as mostly peaceful, this species primarily occupies the bottom and mid-level zones of the aquarium and produces a high level of biological waste.

To thrive, the Bolivian Ram requires a freshwater only aquarium with a minimum volume of 75 litres and a tank length of at least 60 cm. Water temperature should be maintained between 23°C and 28°C, with a pH range of 6–7.5 and a general hardness of 2–10 dGH. A low water flow is preferred.

The Bolivian Ram is a rewarding species to keep, provided its core environmental needs are met. The Bolivian Ram is typically available in one standard form.

When setting up an aquarium for the Bolivian Ram, a low water flow best suits their natural preferences. Because this species occupies the bottom and mid-level zones, the aquarium layout should prioritise open swimming space in the centre of the tank for free movement and sufficient floor space with hiding spots among rocks, wood, or dense planting. Useful additions include a sand substrate to accommodate their sifting behaviour and smooth gravel or rounded substrate to protect their sensitive barbels. Keepers should note that expect substrate disturbance, so lightweight décor should be secured.

Classified as mostly peaceful, the Bolivian Ram is adaptable and can be kept singly or in a small group, offering flexibility when planning a community tank. When choosing tankmates, territorial behaviour may cause issues if hiding spots or floor space are limited. Selecting tankmates that favour different water layers from the bottom and mid-level zones can help reduce competition and territorial overlap.

Bolivian Ram is best for a fishkeeper who wants a species that can settle into a calmer community setup and can provide someone who understands its individual space requirements. It makes the most sense for a hobbyist who will actually build around its needs, especially sand.

The most common mistake is treating Bolivian Ram like any other community fish and skipping the soft sand it needs to forage safely. Another frequent problem is forcing it into an over-busy community when it would do better with more room or more deliberate tankmate choices.
