A charming little cichlid with real character, L. ocellatus is a deservedly popular hobbyists' fish. It has an endearing habit of burying its shell and defending it against all-comers. Many an unsuspecting hobbyist has recieved a sharp nip from an ocellatus who feels its territory is being invaded. Neighbouring shells may also be buried to prevent other fish moving in. Koning has hypothesisesd that the burying of the shell and the resultant pile of sand around it not only provides additiona...

S. ocellifer is often confused with other similar species of Synodontis but can be distinguished by the length of thewhich in this species is very long and runs from just past the base of the to just before the caudal fin. In recent years many alarming hybrids of this species have been appearing on the market and these should be avoided in our opinion. Besides being attractively marked this is one of the hardiest Synos available and is a good choice for the beginner....

It can be distinguished from congeners by the following combination of characters: 61-68 scales in the lateral series; a small, well-defined, sometimes ocellated black spot on the shoulder and another in the centre of the caudal peduncle; body without longitudinal stripes formed by spots on scales; caudal fin uniformly dusky or colourless, lobes without stripes or black margins.

This species is sometimes traded under the names 'mini chocolate gourami', 'Burmese chocolate gourami' or mislabelled as the congener P. ocellatus, these two currently comprising the only known members of the genus. P. lineatus can be told apart from P. ocellatus via the following combination of characters: smaller body size (maximum standard length 18.7 mm vs. 32.0 mm); absence of ocellus-type marking in middle of each flank (vs. presence); presence of dark, stripe (vs. abs...

Some individuals do appear very similar to G. farragus, with noticeable spotting on the head, but can usually still be told apart by examining the caudal-fin which tends to contain only a single thick, dark vertical bar in G. farragus whereas in G. ocellatus there are more often two bars, one thick, one thinner. Intermediate forms do exist though meaning identification is sometimes tricky.

Also known as the beacon tetra, this species is ubiquitous in most dealers' tanks and is one of the best choices for the newcomer to fishkeeping. It's both hardy and inexpensive. It has been popular in the hobby for several decades. There is a selectively bred albino form that has become popular in recent years, for which care is identical to the standard fish. There is possibly also a subspecies, H. ocellifer falsus that lacks the red spot at the caudal peduncle (the gold-coloured tai...

M. ocellatus can be distinguished from congeners by the following combination of characters: caudal-fin rounded; eye stripe not connecting spot on posterior projection of opercle with eye; dorsal-fin rays filamentous posterior to a vertical through the posterior anal-fin rays in adults; 16-19 spinous dorsal-fin rays; 6-13 rakers on ceratobranchial of first gill arch; posterior tip or margin of body scales not darker than scales.

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.

This species is included in the Betta unimaculata complex of closely-related species within the genus, of which members share the following set of characters: body long and slender with depth at dorsal fin origin 18-25 % SL; head large and blunt with width 19-24 % SL; long maxilla and lower lip with distance from tip of lower jaw to posterior end of maxilla 27-54 % HL; caudal-fin rounded in shape, occasionally with elongated median rays; pelvic-fin short and filamentous; dorsal and anal fins relatively pointed.

Peacock Bass are also fished as a sport fish....

One of the smallest species in the genus, it is rarely seen in the trade. A pity, as its diminutive size makes for an ideal aquarium subject. Like others in the suborder Anabantoidei, the species possesses an accessory breathing organ known as the labyrinth organ. So-called due to its maze-like structure, this organ allows the fish to breathe atmospheric air to a certain extent. It is formed by a modification of the first gill arch, and consists of many highly vascularised, folded flaps of sk...

L. kungweensis can be distinguished from similar species such as L. hecqui by the gold colour on the top of the eye. It also has a distinctive black spot towards the back of the dorsal fin. It is not often seen in the hobby....

To date the species is known mostly from the upper Ayeyarwady River basin in northern Myanmar where it's been collected close to the city of Myitkyina in Kachin State as well as around nearby Lake Indawgyi, the largest inland lake in Southeast Asia and home to ten globally threatened bird species. The lake and surrounding area were designated a protected zone by the Ministry of Ecotourism in 1999 and now form the Indawgyi Lake Wildlife Sanc...

This is one of the less commonly seen Pelvicachromis species in the hobby. There are a few morphs available, including "Matadi" and "Moanda". Males and females of these should not be cross bred in order to keep the lines pure. It can be distinguished from others in the genus by it's higher, shorter body shape and by the fact that the spotting in the upper part of the is much lighter in this species than in others. A female condition is hard to confuse with anything else....

This species is one of the smallest and most attractive in the family, and makes an ideal resident of the planted community tank....

This species is also referred to as 'clown knifefish' in the aquarium trade. It arguably has no place in the ornamental hobby given its adult size and specialised requirements but remains inexplicably popular and an albino form has even been line-bred for the purpose. It can be distinguished from all congeners by presence of one or more rows of large ocellated spots above the base of the anal-fin, but...

This rarely-traded species is a member of the H. ocellata 'group' of closely-related congeners, an assemblage which currently comprises H. ocellata, H. bilineata, H. confuzona, H. orthogoniata, H. ogilviei and H. parclitella. Following Tan and Ng (2005) these share possession of a colour pattern with reddish tints and dark brown head markings, elongate head, slightly compressed body, 61-77 lateral line scales and dorsal-fin origin placed in advance of pelvic-fin origin.

This species appears is rare in the aquarium hobby with the majority of images both online and in the published literature instead depicting H. confuzona or H. parclitella. All three are members of the H. ocellata 'group' within the genus which currently contains H. ocellata, H. bilineata, H. confuzona, H. orthogoniata, H. ogilviei and H. parclitella. Following Tan and Ng (2005) these share possession of...

This species is very similar to L. ocellatus and often carries the trade name "black ocellatus". It is found living alongside L. stappersi in nature....
