Lampeyed Panchax; LampeyeAplocheilichthys (formerly Micropanchax) macrophthalmus 30 mm 1 in. Nigeria, Cameroon : forest streams. The body is not cylindrical, but more laterally compressed. Its colour is a delicate blue, with a faint gold line running from the gill cover to the caudal fin. The caudal fin may have a yellow tinge, with red marks at the edge. The eyes are blue. Unlike some Killifishes, this species does well in hard, alkaline water. A shoaling upper water level species, perhaps too small for a community collection. Temperature: 23-26°C (73-78°F). Diet: live and dried foods. Breeding: lays eggs over period of days in plants or mops. Eggs hatch in two weeks and fry mature in six months. (more…)
The young of these fishes develop inside the body of the female until they have absorbed the yolk-sac and are then released. Most livebearing fishes are easily sexed : male fishes have the anal fin modified into a rod-like structure called the gonopodium, through which the fertilizing spermatophores are introduced into the female. Gestation is approximately 3o days and broods may number from 20 to 200. It is possible for the females of some species to deliver successive broods without a repeat mating with the male. (more…)
Fishes in this family are often referred to as ‘labyrinth’ fishes because they have a labyrinthine organ in the head which allows them to breathe atmospheric air if necessary. Another distinguishing feature of this group is the breeding pattern: the majority of the fishes are bubblenest builders. The nests are made of saliva-coated bubbles blown by the male, into which the fertilized eggs are placed following the nuptial embrace beneath the nest. The fry are guarded and kept within the vicinity of the nest by the male. The female is best removed after spawning as the male may attack her. When breeding, care should be taken not to allow any cold draughts of air to pass acrossthe water surface as the fry may become chilled. As it is, a fairly high mortality rate occurs within the first two weeks of life with many species, and the ratio of males to females may be low. (more…)
The majority of African Cichlids inhabit the Rift Valley lakes and are spectacularly coloured. These fishes are from naturally hard waters, unlike their South American relatives, and many relish algae or other vegetable matter in their diet. Some are mouthbrooding, and all appreciate a tank furnished with hideaways.
Aulonacara nyassae 150 mm 6 in. Lakes Malawi (Nyasa) and Tanganyika. Has an elongated, fairly deep body. Young males and females have brown bodies with several vertical dark bars, but mature males are deep royal blue with a red/gold suffusion on the flanks, which are crossed with dark bars. The fins are blue ; the dorsal fin is edged with pale blue and the caudal fin has dark blue/black streaks. A peaceful fish, but caves and hiding places must be provided in a reasonably sized tank. Temperature: 24°C (75°F). Diet: all foods. Breeding: mouth brooder. (more…)
Species of this family are native to South America, Africa, India, Burma, Thailand and Indonesia. Most are aggressive and predatory, but their colours and behaviour ensure their popularity.
Badis; Dwarf Chameleon Fish Badis badis 65 mm n in. India : standing waters. This fish can change its body colours and patterning to suit its surroundings. Generally it is a dark reddish-brown, with a greenish sheen. From time to time transverse bars may appear. The dorsal fin (similar in shape to that of Dwarf Cichlids) and caudal fin are greenish. The female fish is less colourful. (more…)
