Description

Mikrogeophagus altispinosus is a species of fish endemic to the Amazon River basin in Brazil and Bolivia. The species is part of the family Cichlidae and subfamily Geophaginae. It is a popular aquarium fish, traded under the common name, the Bolivian Ram.

The species is similar in profile to the larger geophagine cichlids. Maximum size is about 3.1 inches. The head and front half of the body is yellow, fading to olive-grey at the rear. A vertical black band runs across the eye, and six faint transverse stripes occur along the body; the third stripe is dark at its centre. The first few rays of the dorsal fin are black, and both the dorsal and caudal fin are edged in a pinkish red. The anal and pelvic fins are the same shade of red throughout with bright blue rays and dots.

The species displays only limited sexual dimorphism, mature males being slightly larger and in some cases showing longer extensions on both the caudal fin and the posterior of the dorsal fin. Bolivian rams are biparental, open-spawning cichlids. After courtship, the female deposits some 100–200 ovoid, brownish-coloured eggs on the chosen surface, normally a flattened stone, but occasionally a leaf. In aquariums at 80 °F, eggs take about 60 hours to hatch. During this time, the clutch is primarily cared for by the female, which fans the eggs and often adds sand to the clutch, possibly to camouflage the eggs. Newly hatched fry are transported by the mouths of the parents to the shallow pits dug by the male during courtship and moved regularly between pits. The fry become free-swimming after seven days and are led about in a dense school by the parents for foraging.

Bolivian Rams appear to have a fluid ‘stop-and-go’ method of swimming, in which they typically move for a few paces, pause abruptly, then move again. In this, their bodily control is remarkable in that they appear to not be carried by momentum while stopping; they appear to ‘freeze’ instantaneously in place and ‘hover,’ before moving again. This is likely due to their instinctive drive to sift carefully through substrate for food, so as not to stir up debris with their fins. As such, they are generally bottom-feeders and typically will not venture into the higher regions of the aquarium. Their swimming style is usually gentle and graceful, but they can move surprisingly quickly when evading predators or chasing away territorial invaders.

An aquarium which mimics the natural environment of the species, i.e.: 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 aquaria, with minimum volumes being 20 gal. Omnivorous, this fish sifts the substrate for plant material and small organisms. It is capable of feeding in midwater or on the surface. In captivity, the species is not a fussy feeder and readily accepts many commercially available fish foods.
