Results for “saddle”

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 is the type species of the genus Aequidens and has the widest distribution of any member species. It exists in various colour forms depending on locality with variants from Ecuador and Peru being particularly sought after since they develop striking red (Ecuador) or orange (Peru) colouration on the lower part of the jaw, head and anterior portion of the belly whereas those from Brazil tend to have an overall grey/blue/green colouration, for example. Despite its type status it's long...

This species appears superficially similar to a number of congeners including C. ambiacus, C. agassizii, C. brevirostris, C. delphax, and C. melanistius. Among these C. ephippifer seems to be unique in that all fins except the dorsal are transparent and lack markings.

An incredibly hardy, nocturnal species with very poor vision, P. endlicheri endlicheri relies on its excellent sense of smell to locate food. This species, along with others of its genus, are some of the last surviving relatives of very ancient species. Fossils of earlier relatives have been found that date back to the Triassic Period, which occured during the early development of the dinosaurs more than 200 million years ago. They have several interesting adaptations. The swim bladder is div...

Type locality is 'Eastern Himalayas; small streams below Darjeeling and Sikkim, India', and this species is only known with certainty from upland parts of Assam, Sikkim, Arunachal Pradesh and West Bengal states in northern India. Records from Nepal apparently require confirmation while it may also occur in Bhutan.

This species is also referred to by the alternative vernacular name 'Batik loach' and is the most-commonly traded member of the genus at present. It's easily-distinguished from congeners by body patterning which comprises a series of pale, oblique saddle-like markings edged in black and running along the dorsal surface, plus a similar set of bars originating from the otherwise plain ventral surface.

This species was originally named Nemacheilus masyae but following ICZN rules the spelling was later corrected to N. masyai because it's named after a man. It can be distinguished from the majority of congeners by body patterning comprising 14-18 short, dark vertical bars on each flank, 12-17 saddle-like markings running along the dorsal surface, a dark spot on the caudal peduncle at the termination of the lateral line and a dark blotch in the lower half of the first few dorsal-fin rays.

Patterning is highly variable depending both within and between populations and the species may comprise an assemblage containing a number of taxa (Kottelat and Lim, 1993; Tan and Kottelat, 2009). For example, those from Singapore and Johor possessing intricate mottling on the dorsal surface while individuals from Terengganu have a series of saddle-like markings either alternating or connecting with the midlateral markings.

This species is quite uncommon in the aquarium hobby although its name is sometimes used in reference to the similar-looking, apparently undescribed congener S. cf. balteata, and both are also traded as 'sumo loach', 'tri-banded sumo loach', and 'orange saddle-back loach'. Following Kottelat (1990) it's diagnosed by the following combination of characters: unique colour pattern consisting of two da...

B. sabanus is very similar to B. doriae and these two are easily confused. However in B. doriae most of the first-dorsal-fin and two-thirds of the pectoral-fin are black while in B. sabanus the last one or two rays of the first dorsal-fin are colourless and less than half of the pectoral-fin is black. In addition there are usually smaller dark 'saddles' betw...

Also known as the painted, saddle or marbled sailfin catfish, it's debatable as to whether this species should be considered an aquarium subject at all given its eventual size. All too often, juveniles are sold without adequate information regarding their long term care. These cats can and will attain something close to their maximum size in captivity, and will do so quite quickly. The myth that they will only grow to match the size of the tank they're kept in is just that. It's a...

The similar-looking N. masyai is sometimes traded as N. pallidus, but the two can be told apart by body depth (14.8-19.1 % in N. pallidus vs. 12.6-17.6 % SL in N. masyai), interorbital width (5.7-8.0 % vs. 4.9-6.8 % SL) and the fact that in N. pallidus the dark body bars and saddles are thinner than the light-coloured interspaces between (vs. wider in N. masyai).

This species can be distinguished from all congeners except P. bachi and some specimens of P. furcata by possessing only faint spots and saddles on the body. It can be told apart from P. bachi by possession of narrow (vs. wide) pelvic-fin spines, having the eyes positioned high (vs. low) on the head, and distinctly round (vs. appearing more as a mottling) spots on the body.
