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.

Endemic to Lake Malawi where it was described from and only occurs around 'Chitendi Island', now normally referred to as Chitande island plus a short stretch of coastline between Ngara and Chilumba along the lake's northwestern shoreline.

Batasio havmolleri (Smith, 1931) is currently considered a junior synonym of B. fluviatilis. Members of the genus Batasio are characterised by the following combination of characters; laterally-compressed body shape; presence of large sensory pores on the head; a narrow mental region; a pair of prominent posterior proces...

Members of the genus Batasio are characterised by the following combination of characters; laterally-compressed body shape; presence of large sensory pores on the head; a narrow mental region; a pair of prominent posterior processes on the anterior portion of the vomer; a transversely elongated, bar-like entopterygoid; close contact between the metapterygoid and quadrate.

This species is very rare in the trade and is normally imported only as bycatch among shipments of other fishes. It can be told apart from its well-known congener B. dorsiocellata by a combination of characters as follows: lateral line complete (25-30 pored scales vs. 4-9); more scales in the lateral row (29-32 vs. 25-27); larger adult siz...

An incredibly hardy species, the walking catfish is tolerant of a very wide range of water chemistry and temperature. It can also survive in oxygen-depleted conditions due to its ability to breathe atmospheric air. In fact, it is thought that the fish can literally drown if deprived access to the water surface for long enough. The common name is derived from its natural ability to move across land using its stiff pectoral spines, provided it stays damp. It has special mucous-producing pores ...

This species is sometimes referred to as 'Hora danio' or Salween danio'. It is distinguished from similar-looking species by a combination of characters as follows: lateral line complete or incomplete with 22-33 pored scales; absence of infraorbital process; 7 branched dorsal-fin rays; usually 10 or 11 branched anal-fin rays; barbels absent or rudimentary; flank markings comprising a series of narrow vertical bars on the anterior portion of each flank, fol...

This species is traded under various names including 'Vietnamese multi-banded zebra loach', 'hovering zebra loach', 'Laos pygmy multi-stripe loach', and 'banded dwarf loach'. It can be distinguished from related species by the following combination of characters: body with distinct vertical bars; 8 branched dorsal-fin rays; 3-10 pored lateral line scales; one pair of large papillae in median portion of upper lip; two pairs of large papillae in median portion of lower lip; lower posterior edge of opercle with 3-4 prominent indentations.

Following Bonou and Teugels (1985), P. africana can be distinguished from congeners by the following combination of characters: colour pattern unique, comprising a series of 8-11 dark, chevron-shaped markings extending along the body posterior to the pectoral fins; 19-24 scales in the transverse series; lateral line complete with 73-83 pored scales; 45-48 dorsal-fin rays 45-48; 32-35 anal-fin rays.

P. chola was retained in Puntius sensu stricto, of which members are defined by the following combination of characters: adult size usually less than 120 mm SL; maxillary barbels absent or present; rostral barbels absent; 3-4 unbranched and 8 branched dorsal-fin rays; 3 unbranched and 5 branched anal-fin rays; last unbranched dorsal-fin ray weak or strong and unserrated; lateral line complete with 22-28 pored body scales...

It can be told apart from similar-looking congeners such as P. crescentus and P. muzaffarpurensis by the following combination of characters: barbels absent; lateral line incomplete with up to 5 pored scales; 20-22 lateral line scales; 8 predorsal scales; dorsal-fin with a vertically-orientated black streak and a black tip with orange markings; a dark spot at the base of the caudal peduncle.
