Results for “caudal peduncle”

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.

This species is not especially popular in the hobby and is only infrequently seen on sale. It is clearly distinguishable from similar-looking members of the genus by lacking a dark stripe along the lateral line. Instead it possesses two spot-like markings on each flank, one below theorigin and lateral line and another at the caudal peduncle. The intensity of these can vary depending on the collection locality of the fish and they can be quite faint in some forms. There is also a third, smaller m...

It is unclear if this species has been available in the aquatic trade as collections from its native waters only occur sporadically, therefore we have based much of the information here on experience with its closest relative R. kalochroma. These two are almost identical in appearance and share some meristic features but R. kottelati possesses an additional, oval-shaped dark blotch on the caudal peduncle, lacks the stripe in the middle of the seen in R. kalochroma and is consequently easy to dis...

This species is very rare in the aquarium trade but available on occasion. It has 8-9 darkish body bars which usually split vertically as the fish mature, and like some conspecifics possesses a prominent dorsal adipose crest on the caudal peduncle. Schistura is the most species-rich genus among...

Can be told apart from congeners by its colour pattern which consists of 8-11 closely-set, narrow dark bars in the anterior part of the body and 5 wider bars in the posterior part. It also possesses prominent dorsal and ventral adipose crests on the caudal peduncle and 9½ branched dorsal-fin rays.

Y. eos isn't as commonly-traded as it once was but is still available occasionally. It's difficult to confuse with any other member of the genus due to its colour pattern consisting of yellow to reddish brown base body colour (can appear greyish in some specimens, especially post-import or when introduced to a new aquarium) with a metallic green/blue golden sheen and large darkish marking on either side of the caudal peduncle. The fins can be yellowish to reddish, and the dorsal and c...

This species is included in the B. pugnax complex of closely-related species within the genus, an assemblage of which members are notoriously difficult to tell apart from one another, but which can be characterised collectively by the following set of shared characters: relatively large head measuring 28-40% SL; live colouration usually brown with green or blue iridescent spots; male with similarly-coloured scales on opercle, sometimes extending to abdomen; juveniles and females usually brown with two central body stripes and a dark marking on the caudal peduncle; anal-fin in mature specimens pointed and often elongated; caudal-fin lanceolate.

Can be hard to find in aquarium shops, and there has been some confusion surrounding its identity in the past. Base body colour is either powdery-blue or yellow-green (see 'Distribution') and this continues into the caudal-fin, while pinkish-yellow lateral stripes extend from opercle to caudal peduncle.

This species is so ubiquitous across its natural range that it's often referred to simply as 'common barb'. Basic adult colour pattern consists of a small, dark spot at the base of the dorsal-fin origin and another on the caudal peduncle but overall appearance varies somewhat depending on origin, with the anterior dark spot enlarged ventrally forming a bar or posterior spot extending into the caudal-fin, for example. The spots may also appear darker or lighter in some individuals.

The most recent diagnosis appears to be that of Géry (1977), in which it was separated from other members of the group by the following combination of characters: dorsal-fin insertion at or slightly anterior to mid-body; caudal-fin brick red to orange-red; body depth fits less than 3.6 times in SL; head length fits 3.5-4.0 times in SL; caudal peduncle length u...
