This species is sometimes confused any of several similar-looking fishes such as C. sychri or C. sp. C097. While the former is a more elongate fish with a longer snout and quite easy to identify, C097 resembles C. atropersonatus more closely, despite being traded as C. sychri 'longnose'. Its snout is longer than that of C. atropersonatus but shorter than that of C. sychri, and the dark spots on the body tend to be more well-defined and spaced out than in the other two.

The congener C. seussi, which is also native to the rio Mamoré, has a similar colour pattern but its snout is noticeably prolonged compared with that of C. gossei, plus there are some subtle differences in pigmentation. There is a third variant which has been referred to as 'CW069' in the aquarium hobby and appears to be somewhat intermediate, with a short, rounded snout as in C. gossei but a colour pattern more reminiscent of C. seussi.

G. bispinosa can be distinguished from all other congeners in Southeast Asia and China by the following combination of characters: a conspicuous, quadrate, anteriorly-directed proboscis orientated ventrally against the snout and anteriorly adorned with a single, large, uniscupid, acanthoid tubercle on the distal tip of each lobe; snout with a deep groove across its tip to form a transverse lobe; 34-35 lateral...

G. salweenica can be distinguished from other congeners inhabiting the Salween watershed by the following combinatuion of characters: body brownish; presence of a trilobed proboscis on the snout; snout blunt; a series of black spots at the base of the central dorsal-fin rays; presence of longitudinal stripes on the posterior portion of the body; a dark marking at the tip of the upper (and lower in some specimens) caudal-fin lobe; body depth 22.4-25.3 % SL.

This species can be distinguished from other members of the genus by the following combination of characters: absence of dark spots on body in adults; body elongate with slightly convex dorsal profile; head longer than body is deep; snout much longer than postorbital head length; lips well developed, lateral lobes of lower lip broad and thick with folds, median process small; barbel thickness shorter or equal to eye diameter; dorsal spine strong, ⅔ of HL; dorsal-fin origin closer to tip of snout than caudal-fin base base; 15+ gill rakers; 6½ branched anal-fin rays; posterior simple dorsal-fin rays ossified and spinous.

This species is a member of the putative A. nasutus group of closely-related species within the genus alongside A. nasutus, A. maculipinna and A. isalineae. These are characterised by possession of two dark, longitudinal stripes, one running from the tip of the snout to the base and the other from the posterior edge of the lower maxilla to the underside of the caudal peduncle.

This species is a member of the putative A. nasutus group of closely-related species within the genus alongside A. nasutus, A. maculipinna and A. isalineae. These are all characterised by possession of two dark, longitudinal stripes, one running from the tip of the snout to the base and the other from the posterior edge of the lower maxilla to the underside of the caudal peduncle.

This species is exceptionally rare in the aquarium trade and can be distinguished from congeners by the following combination of characters: snout narrow with head appearing triangular as a resul...

Prior to its description this species was considered a geographic variant of A. iberus but the 2002 paper revealed the pair to be genetically quite distinct and also highlighted some morphological differences. It is distinguished from A. iberus by possessing 8-9 (usually 8 ) branched dorsal-fin rays (vs. 8-9, sometimes 10), 9-11 branched anal-fin rays (vs. 8-9), a deeper, more elongate body shape, noticeably shorter snout, relatively thick (vs. thin) vertical bars in males and a flank patterning consisting of a few la...

This species may also be sold variously as 'yellow regal cichlid', 'Baensch's peacock', 'sunshine peacock' and 'Nkhomo-Benga peacock'. The easiest way to distinguish it from similar-looking congeners is to look at the profile of the snout, which is steeper and more curved than that of its congeners. Aulonocara spp. are benthophagous by nature employing a method of feeding whereby mouthfuls of substrate are taken and sifted for edible items with the remaining material expelled via the gills and mouth. They're equally-skilled at hunting as grazing, tending to hover above the substrate until tiny movements are detected, and possess enlarged sensory pores on the head which assist in this technique.

This species exists in two distinctive phenotypes, with male individuals from West reef and Eccles reef possessing a bright yellow stripe of colour running from the tip of the snout over the anterior portion of the dorsal surface and along the distal margin of the dorsal fin. This form is commonly referred to as 'sulphurhead' or 'sulfurhead' in the aquarium hobby. At Kande Island males exhibit a similar overall colour patterm but the dorsal stripe is whitish in colour and both males and females possess an enlarged lower pharyngeal bone. This population was described...

It can be told apart from other members of the B. pugnax group by the following characters: caudal fin rounded in both males and females; chin bar and second postorbital stripe absent; adult males possess intensive blue or bluish-green iridescent (blackish in preservation) colouration on the sides of the head and throat extending from the snout tip to posterior edge of opercle; possession of two central body stripes, the upper extending from the pec...

Boulengerella differs from Ctenolucia, the only other genus currently contained in the family Ctenolucidae, by a series of derived features including possession of 87-124 (vs. 45-50) lateral line scales, presence of a strongly (vs. weakly) developed fleshy appendage at the tip of the snout and absence (vs. presence) of fleshy flaps on the lower jaw. Within the order Characiformes the family Ctenoluciidae is also distinguished by a set o...

This species is only occasionally offered for sale, as it is difficult to collect, living a predominantly solitary lifestyle. As a result, it is much sought after by enthusiasts. It may be confused with the other species in the genus, C. caerulus, but can be distinguished by its deeper body shape and very distinctive black markings on its snout. Champsochromis have widely spaced teeth compared to some other pelagic predatory cichlids found in Lake Malawi, such as Buccochromis species....

C. caudimaculatus may be confused with the congener C. similis but can be told apart by possession of a well-defined, blackish spot on the caudal peduncle vs. a 'smudged' bluish marking. C. guapore also has a comparable colour pattern but possesses a distinctly rounded snout and tends to swim above the substrate.

This species occurs alongside the similar-looking congener C. oiapoquensis in nature, from which it can be told apart by the following combination of characters: larger adult size; narrower body (body breadth fits 4.0-4.4 times in standard length vs. 3.4-3.8 times in C. oiapoquensis); shorter pectoral spine (3.4-3.8 times in SL vs. 2.7-3.2 times); longer snout (1.7-1.9 times in SL vs. 2.0-2.2).

Unfortunately, precise diagnostic characters cannot currently be provided since we’ve been unable to obtain the type description, and little has been Characters said to separate it from species such as C. ambiacus, C. agassizii, C. brevirostris, C. ephippifer, and C. melanistius include a combination of relatively elongated snout, dark spots on body fading in adults, dark anterior dorsal-fin patch extending to upper extremity of fin, and presence of spots in the caudal-fin.

It can be distinguished from the majority of other Corydoras species by its distinctive colour pattern, comprising a uniform, lightish base pigmentation with a dark arched stripe extending over the upper portion of each flank, from the tip of the snout to the caudal-fin base. This is shared with a few congeners, however, including C. arcuatus, C. narcissus, and C. urucu.

This species occurs alongside a near-identical congener, C. condiscipulus in nature. In fact condiscipulus literally means 'schoolmate', as the species are often found shoaling together. The only external difference between the 2 seems to be the longer snout and wider distribution within the Rio Oyapock of condiscipulus....

Very similar in appearance to C. gossei, seussi can be distinguished by its less rounded snout. It may also be referred to by its C-number, C027.
