Companions

The Bolivian Butterfly is slightly more aggressive that the Blue Ram, but I still definitely class them as community fish.  They may not be safe companions for the smallest tetras and Danios, but can be kept without problems with most community fish, including other types of peaceful dwarf cichlids.

This fish is not suitable as a companion for aggressive fish.

In the wild there is evidence that this fish is often found by itself rather than with a group of its own species, and they mainly come together for breeding.  But in an aquarium a group of this species does seem to swim together, especially when they are young, and they look very nice.  If keeping a group, it is better to have more females than males.

Fighting

With more than one male in the tank, some minor fighting may occur which may include mouth wrestling.

Sexing

The Male is larger than the female and has more pointed dorsal and tail fins.  He is also more colourful.  In breeding condition, the colours of both sexes are stunning in their brightness, but the male’s colours are generally brighter.  The female gets plumper when loaded with eggs.

Anal Fin

The anal fin of the male is more pointed with more obvious angles and is squarer than the longer more rounded anal fin of the female.

Breeding Tube

Just in front of the anal fin is a little bump.  In the male it is smaller and more pointed than in the female whose breeding tube bump is larger and more rounded.  The actual breeding tube emerges when the pair is almost ready to breed.

Water Conditions

This fish may decide to breed with any water parameters, but seems more likely to with a temperature of about 28 degrees C (86 degrees F), and soft slightly acidic, or neutral, water.

This fish will often attempt to breed in a community aquarium and will sometimes succeed.  They are more likely to get a larger number of fry surviving in a specially set up breeding tank.  This is a less natural way of breeding than in with other fish.

This fish needs to form pairs by itself and our attempts at selecting suitable mates will not always meet with the approval of the fish.  The usual way of getting one or more pairs is to start off with a group of young Bolivian Butterflies, and let them sort themselves out into pairs.

Monogamy

They breed in pairs, not in groups, and display a high level of monogamy, often bonding into pairs for life.

Open Spawners

The Bolivian Butterfly spawns on a surface on the open, choosing a flat rock or pebble, or sometimes a large flat leaf.  This is in contrast to the types of fish that prefer to spawn in caves.

Territorial

The pair of fish will choose and defend a territory in the tank.  In this territory they will choose a nesting site which is often a flat stone.  Both prospective parents clean the surface of the nesting site, and often also excavate several shallow pits in the sand or gravel.

Display

The male will display his gorgeous colours to the female.  While the preparations are proceeding the male becomes more aggressive than usual to other fish in the aquarium.  The male and female will swim alongside each other, displaying their increasingly bright colours.  The courtship may last a few days.

Trials

The female will often do a few trial runs over the nesting site while the male watches her.  At this time both fish will have protruded their breeding tubes.  The female’s tube is thicker than male’s and is blunt while the thinner tube of the male is pointed

Spawning

The female lays her light grey eggs a few at a time.  She often does this in a pattern on the nesting site.  Sometimes she might lay them in straight lines with the male moving in to fertilize each row after it is laid.  Other females might lay the eggs in a circle

The spawning may take an hour or more, and usually between 50 and 300 eggs are laid.

Guarding

The female takes her station over the eggs guarding them and also fanning them with one pectoral fin.  The male spends most of his time guarding their territory, but may relieve the female for short periods.

Hatching

The eggs hatch faster at higher temperatures, but they usually take about 48 hours to hatch.  Females have been observed helping their babies to get out of the eggs.

At this stage the babies are still living on the food reserves of the eggs and are not free swimming.

Transfer

The female takes the babies into her mouth and transfers them to one of the pits that the couple prepared earlier.

She may transfer the babies several times to different pits.

Free Swimming

It takes between 5 and 8 more days for the fry to become free swimming.

The fry are very active, and will follow the parents, often in a tight school.  They are very vulnerable to predation by other fish in the tank.

As soon as they are free swimming, the fry are big enough to eat newly hatched brine shrimp.  Other suitable foods include micro worms, infusoria and commercial fry foods, both the dry ones and the liquid sorts.

In six months the babies should be about 4 centimetres (1.5 inches) long.

Clean Water

The fry are particularly susceptible to dirty water, and care must be taken to keep it clean.  Very frequent partial water changes should be done.  Ammonia and nitrites are very poisonous to the young fish, and nitrates will severely slow their growth if allowed to get above about 20 ppm.

Learning

The whole process of spawning and raising babies is complicated for this fish and they usually do not get it completely right the first time and have to start again with another batch of eggs.  They seem to improve considerably with practice.  If eggs are infertile they will turn white.

Conservation Status

Mikrogeophagus altispinosus has not been evaluated for the UICN Redlist, but there is no reason to think its existence is threatened in the wild.

Scientific Name

The accepted name of this species is Mikrogeophagus altispinosus (Haseman, 1911.)  Other names that have been used include Crenicara altispinosa  (Haseman, 1911),Microgeophagus altispinosus (Haseman, 1911) and Papiliochromis altispinosus (Haseman, 1911.)

Common Names

In German, the Bolivian Butterfly is called Der “Bolivianische Schmetterlingsbuntbarsch”, in Denmark and Norway it is “Boliviansk sommerfuglecichlide”, in Finland it is “Rusokirjoahven” in Poland it is “Pielęgniczka boliwijska”, in Thialand it is “ปลาหมอแคระแรมโบลิเวีย” and in China it is either “高棘小噬土丽鲷" or “高棘小噬土麗鯛”.

Pest Fish

As with any animal, normal precautions should be taken to prevent this fish getting into ecosystems it is not native to.
