Although less popular than its close relative Mikrogeophagus ramirezi, the Bolivian ram remains a commonly encountered cichlid for the aquarium. The species is also more tolerant of lower temperatures (22-26 ºC, 72-80 ºF) and a greater range of water chemistries than M. ramirezi. For these reasons, M. altispinosus can be kept in some community aquariums, however, assertive, active or aggressively-feeding fish are not ideal companions for this relatively shy species. An aquarium which mimics the natural environment of the species, ie: soft, acidic water with hiding places in the form of dense planted regions, or bogwood is recommended. Aquarists classify M. altispinosus as a dwarf cichlid and as such it can be kept in relatively small aquariums, with minimum volumes being approximately of 80 litres (20 gallons). In captivity the species is an unfussy feeder and readily accepts many commercially available fish foods.
