Kindom: Animalia
Phylum: Chordata
Class: Actinoptergii
Order: Perciformes
Family: Cichlidae (cichlids)
Subfamily: Etroplinae

Genus/species: Paretroplus menarambo

GENERAL CHARACTERISTICS: When young, Mearambos are a pale gold with black dots in a pin stripe pattern. As they reach adulthood, around 4 inches or 3 years of age, they are blue/gray to almost white with black dot pin stripes. The fins are edged in red, especially the tail. Max length : 12.8 cm (5 in).

DISTRIBUTION/HABITAT: Endemic to Madagascar. Present in the freshwater flood plain lakes of the Bemarivo River, the major northwards-flowing tributary of the Sofia River in northwestern Madagascar. The species is now known to occur in a single lake of that system: Lac Tseny.

DIET IN THE WILD: Have teeth specially designed for crushing snail shells.

REPRODUCTION: Substrate spawner. Eggs are laid in a pit and will adhere to surfaces such as driftwood.

PREDATORS: Critically endangered species threatened by invasive species and over-fishing.

CONSERVATION: IUCN Red list: Critically Endangered (CR)
No data are available on the wild population; previously it was thought to have disappeared from its native range, but more recent surveys rediscovered the species in Lac Tseny Habitat degradation, the presence of invasive exotic species and overfishing account for its Critically Endangered status. Breeding populations of this species are maintained in captivity.

Phylum: Chordata
Class: Actinoptgerygii
Order: Periciformes
Family: Chichlidae (Cichlids)

Genus/species: Paratilapia polleni

GENERAL CHARACTERISTICS: Mid-sized cichlid, growing to 30 cm (12 in) in length; males grow up to a third again as large as females; black velvet basic coloration with pattern of blue and gold spangling. Distinct spot present in dorsal fin of juveniles and sexually quiescent adults.
Adult male fish are much larger than females and develop longer extensions on the dorsal and anal fins. They also tend to have a more rounded head shape.


DISTRIBUTION/HABITAT: Endemic to Madagascar found in freshwater at altitudes up to 1,500 m (5000 ft) and exhibit tolerance for a broad temperature range.

DIET IN THE WILD: Carnivorous, juveniles feed chiefly on planktonic crustaceans and insect larvae; larger fish are crepuscular predators with a preference for small fishes, but also take invertebrates as opportunity presents.

REPRODUCTION: Marakely parenting is a two-fish job. They are monogamous, biparentally custodial substrate spawners. Pairs defend a territory and both sexes assume a velvety black base coloration as spawning approaches. They excavate a gravel pit and spawn in it excluding other fish from area. Each egg has a long adhesive fiber that adheres to other egg fibers, forming a rope of eggs (up to a thousand) rolled into an egg mass. The male patrols the perimeter of the territory as the fry become mobile four days post-hatching. Both parents follow the school of fry, retrieving stragglers by mouth and spitting them back into the school. Parental care continues for about three weeks. These protective behaviors promote reproductive success common to many cichlid species.

PREDATORS: In the southern part of its range, the exotic spotted snakehead is both a competitor and predator. Paratilapia polleni have lived for up to 15 years in aquariums.

CONSERVATION: IUCN Red List; Vulnerable (VU)   Qualifies as Vulnerable on account of its limited distribution and fragmented habitat (mainly due to deforestation of river catchments) which are causing a continued decline in available habitat and the number of mature individuals in the population. 

A Marakely captive breeding program is supported by many aquariums and zoos.

REMARKS. The most primitive living representatives of the large Cichlidae family.  Some of Madagascar’s freshwater fish species have ancestors dating back to the Jurassic period.

Genus/species: Ptychochromis grandidieri

GENERAL CHARACTERISTICS: Yellowish to golden base coloration with a horizontal series of well-defined black blotches situated mid-laterally on the flank. Length to 21 cm (8.25 inches).

DISTRIBUTION/HABITAT: Eastern drainages of Madagascar. Found in fresh water in areas of high forest as well as brackish water.

DIET IN THE WILD: Invertebrates, plant materials.

REPRODUCTION: Egg layers; both male and female care for fry. The rate of breeding would allow the population to double in less than 15 months.

CONSERVATION: IUCN Red List Least concern (LC)  Common throughout its range, which extends along much of eastern coastal Madagascar. Vulnerable to introduced Asian snakehead fish.

KINGDOM      Animalia

PHYLUM        Chordata

CLASS           Actinopterygii  (ray-finned fishes)

ORDER          Percifomes  (Perch-likes)

FAMILY         Cichlidae  (Cichlids)

GENUS/SPECIES  Katria katria



Katria katria  has a unique pattern of two prominent black vertical bars on an iridescent golden background. Max length: 5.5 cm (2 in).



One of 17 cichlid species indigenous to Madagascar.

Lives in freshwater pools, slow flowing runs and rapids with predominantly sand and gravel substrate, with a few very large rocks.





Substrate spawner. Pairs of Katria have been observed guarding either eggs or small juveniles close to the top of the rocks in the Nosivolo Rver in November, 2005.



IUCN List: Vulnerable.

This species has a restricted distribution within the Nosivolo and Mangoro rivers, but its habitat is in very good condition and it does not have to deal with either exotic predators or competitors. Given the lack of evidence for decline in quality of habitat or population size (it is a very common species within its range), this species is assessed as vulnerable on account of its restriction to a single location.
