About
Mikrogeophagus altispinosus is a small cichlid from the upper Madeira basin, specifically the Rio Mamore and Rio Guapore drainages of Bolivia and Brazil. FishBase records 5.6cm standard length and Seriously Fish gives 8cm. A black bar crosses the eye and a dark blotch marks the flank, while the throat, belly and fins carry yellow and red. It tolerates a wider range of water chemistry than its congener M. ramirezi and is markedly hardier, though it is not a fish for a general community tank. Aquarium conditions are 24-28C, pH 6.0-7.5 and 1-10dGH, with a 90 x 45cm base and roughly 182 litres as the guide. It sifts mouthfuls of substrate for food, so a deep layer of fine rounded sand is important. Pairs are biparental substrate spawners; eggs hatch in 2-3 days and the fry stay immobile for 5-8 days before swimming. The IUCN Red List assesses it as Least Concern.
