Gold Saum

March 13th, 2012 — 1:19pm

Native to extreme northern Peru and coastal drainages of western Ecuador as far north as the Río Esmereldas drainage and possibly beyond. The form from the Esmereldas and above may represent a different species (see ‘notes’).

Astronotus ocellatus (AGASSIZ, 1831)


March 13th, 2012 — 1:19pm

This species is also referred to as ‘velvet cichlid’, ‘red oscar’, ‘tiger oscar’, or ‘marble cichlid’.

It is a popular aquarium fish although its adult size and typical life-span of 10-20 years must be taken into account before purchase. Numerous ornamental strains are now available, and while care is more-or-less identical for all of them a degree of additional care must be taken with the ‘long-finned’ variety which is a little less competitive than other forms.

Thorichthys meeki BRIND, 1918

Firemouth Cichlid

March 13th, 2012 — 1:19pm

This species has been a popular aquarium fish for a considerable period and virtually all fish traded are now raised commercially for the purpose.

It is easily identified by the characteristic bright red or orange underside of the head, which is more pronounced in adults.

Following Miller and Taylor (1984), the genus Thorichthys is identified…

Amphilophus labiatus (GÜNTHER, 1864)

Red Devil

March 13th, 2012 — 1:19pm

Previously included as a member of the genus Cichlasoma, the red devil is often confused with the midas cichlid, A. citrinellus. The two can be distinguished through differences in morphology. As suggested by its scientific name, A. labiatus possesses characteristically large lips, although in reality this is variable and should not be used as a defining indicator of species. Certainly, tank bred fish tend not to have these large lips. More reliable differences include the bigger nuchal hump and mo…

Anomalochromis thomasi (BOULENGER, 1915)

African Butterfly Cichlid

March 13th, 2012 — 1:19pm

Often overlooked when seen for sale, as juveniles can appear a little dull, A. thomasi is actually one of the best choices for the newcomer to dwarf cichlids. It is relatively undemanding, peaceful, easily bred and quite beautiful once settled into the aquarium.

The species is currently monotypic, although several colour forms are available from time to time. In the future some or all of these may prove to be distinct species….

Amatitlania nigrofasciata (GÜNTHER, 1867)

Convict Cichlid

March 13th, 2012 — 1:19pm

A hugely popular and very adaptable species, the convict is one of the most ubiquitous fish in the hobby. It is often referred to by synonyms such as Cryptoheros nigrofasciatus and Cichlasoma nigrofasciatus. It's difficult to know how much to recommend it to the beginner, as despite its hardiness and ease of breeding, it's not really a community fish. However, if you want to breed a species and witness some amazing parental behaviour, it's an unreserved recommendation. It now exis…

Rocio octofasciata (REGAN, 1903)

Jack Dempsey Cichlid

March 13th, 2012 — 1:19pm

A bright blue variant normally referred to as ‘electric blue Jack Dempsey’ or simply ‘EBJD’ is of unclear origin but it appears to be an ornamental strain fixed from a natural mutation.

Care is as per the natural form although the blue fish tend to remain smaller and some reports suggest them to be less aggressive.

R. octofasciata has a confusing taxono…

Geophagus altifrons HECKEL, 1840

March 13th, 2012 — 1:19pm

Despite its designation as type species this is among the most frequently-misidentified members of the genus.

This is in part because its natural distribution was earlier considered even more extensive than the still-substantial range recognised today, with populations from the Río Orinoco, Guianas and rio Tocantins now recognised as species in their own right.

Geophagus winemilleri LÓPEZ-FERNÁNDEZ & TAPHORN, 2004

March 13th, 2012 — 1:19pm

This species is rare in the hobby although other species are sometimes sold under the name. It’s a member of the nominal G. surinamensis ‘group’ of closely-related species within the genus and can be identified by a combination of characters including: possession of dark preopercular marking; four parallel, ventrally-inclined bars on each flank (normally visible only when the fish are stressed, spawning or preserved); dark lateral spot positioned within the second vertical bar; caudal fin red with variable pattern of large, iridescent blue to white spo…
