Results for “sp.”

Omnivorous and will accept most foods offered, with the stomach contents of wild specimens varying on a seasonal basis but mostly comprising insects and insect larvae (orders Trichoptera, Hemiptera, Homoptera) plus some terrestrial fruits and even scales of other fishes (Sánchez et al., 2003). In the aquarium offer live Daphnia, Artemia, Moina, bloodowrm, etc., vegetable matter in the form of blanched spinach, lettuce, cucumber, fruit, algae wafers, etc., and good quality, sinking dried foods.

C. brevirostris was described from an aquarium specimen apparently exported from the Río Orinoco drainage in Venezuela, and its wider distribution is somewhat vague, usually being given as the Orinoco system plus unnamed coastal rivers in Suriname. This represents a somewhat disjunct pattern of distribution and if correct the species is also likely to occur in Guyana.

It exhibits slightly different behaviour to the majority of congeners in that it tends to swim in midwater and spends a large proportion of its time away from the substrate. Its morphology exhibits corresponding adaptations towards a pelagic existence with a relatively large eye, a more terminal mouth position, more strongly-forked caudal-fin, and more symmetrical body shape than most other Corydoras species.

This fish remains in need of identification, and we've chosen to list unidentified members of the genus using an 'ER' numbering system in the absence of definitive information. It's quite easy to distinguish from congeners since it's the only species known to possess a colour pattern comprising a dark base colour and series of thin, paler vertical bars on the body and similarly-coloured spots on the head.

This stunning species must surely rank among the most attractive Loricariids available in the hobby. There are several colour forms available, depending on collection locality. These vary in base colour and in the number, size and positioning of the spots on the body. The true identity of this fish is shrouded in confusion. It may or may not be Hemiancistrus subviridis, also known as the green phantom plec (L200), which it resembles very closely in morphology. The two are also found in diffe...

A rarely seen, although attractive member of the severum family. This species is occasionally offered for sale through specialist cichild or South American dealers.

This is an excellent beginner's species as it is relatively peaceful and easily bred. Despite being undescribed to science it is widely available in the hobby. It is sometimes sold as Gephyrochromis acei. Several colour forms are available, including "yellow tail acei" and "white tail acei". None of these should be kept together in aquaria to prevent hybridisation. In nature it feeds specifically on algae and other organisms growing on submerged wood, and is the only ...

Some wild populations have evolved a complex amphidromous breeding strategy in which adults live and spawn in freshwater or brackish streams and the pelagic post-hatch larvae are washed downstream to the sea where the post-larval fry spend the first part of their life developing in estuarine nursery zones under brackish to full marine conditions. Once they reach a certain stage of development they begin to migrate upstream with some mov...

This fish was collected for the aquarium trade during 2012 but its identity has not yet been established. Schistura is the most species-rich genus among nemacheilid loaches with some 190 members and it continues to grow with over 100 having be...

This species first became available in early 2010 and sometimes appears on trade lists under the vernacular names 'Laos sucker' or 'Laos Sakura sucker'. It's distinguishable from other members of the genus by the following combination of characters: body spotted and without stripes; no concentric bands on paired fins; origin of pelvic-fin below origin of dorsal-fin; origin of pectoral-fin posterior to corner of mouth; pelvic fin reaching origin of anal fin; small elevated ...

This species is rare in the hobby although other species are sometimes sold under the name. It's a member of the nominal G. surinamensis 'group' of closely-related species within the genus and can be identified by a combination of characters including: possession of dark preopercular marking; four parallel, ventrally-inclined bars on each flank (normally visible only when the fish are stressed, spawning or preserved); dark lateral spot positioned within the second vertical bar; caudal fin red with variable pattern of large, iridescent blue to white spo...

This unidentified species was originally traded under the C-numbers C115 and C116 but these two are now thought to represent the same species, while fish collected from Manú National Park and sold as C. sp. 'Manu 1 long nose', C. sp. 'Manu 4', C. sp. 'Manu 7', and C. sp. 'Manu 8' may represent this species as well. It's highly variable in terms of colour patter...

There are currently 4 described subspecies of Melanotaenia splendida. The principle differences are generally in colour, pattern and fin counts, although even these vary depending on the locality of the fish. M s. splendida in particular also exhibits a wide variation in colour and patterning depending on locality within the subspecies, and the species name is often suffixed with a place name when the fish are seen for sale. The different forms and subspecies should not be mixed in the aquarium,...

Juvenile specimens are occasionally available in the aquarium trade but this species is clearly not a viable subject for the vast majority of private aquarists. While it's considered a sport fish in some countries (France, Italy, Spain, UK) it's flesh and eggs are considered a delicacy in others (Hungary, Poland, Slovakia, Lithuania) and its skin is also used in the manufacture of leather and glue. The family Siluridae comprises those catfsh species commonly referred to as freshwate...

This species is often confused with B. krataios in the aquarium trade, the latter having been known as B. sp. 'Kapuas' prior to description. The two can easily be told apart as the caudal-fin is rounded in B. krataios but spade-shaped and in adults, highly-extended in B. dimidiata. Together these two comprise the B. dimidiata group of closely-related species within the gen...

This species was traded as B. sp. 'Kapuas' prior to its formal description and continues to be mislabelled B. dimidiata. The two can easily be told apart as the caudal-fin is rounded in B. krataios but spade-shaped and in adults, highly-extended in B. dimidiata. Together these two comprise the B. dimidiata group/complex of closely-related species within the genus, members of which can be characterised b...

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.

This undescribed species has been available in the aquarium hobby since 2006. It may also be seen on sale with the name Badis sp. 'flame dot' in reference to the body scales which in males possess a bright red centre or B. sp. 'red' as it appeared in a 2007 German magazine article. It appears to belong to the B. corycaeus group of species (see below). Since the species Badis singenensis was...

This potentially-undescribed species first became available in 2002, and males and females were marketed as 'Danio sp. hikari yellow' and 'D. sp. hikari blue', respectively. Subsequent DNA testing in the United States revealed them to be the same species and genetically distinct from the very similar B. kerri. It can be told apart as the central body (P) stripe always extends into the caudal fin whereas in B. kerri it terminates at the caudal peduncle. Only a single population of B. kerri was sampled in the stu...

Also known as the Domino Synodontis or the One-spot Squeaker, several regional variants of S. notata are known, some of which have 3, 6 or 12 spots and others none at all. Some of these are seen for sale under the invalid name S. ocellata. It is also often imported with similar species such as S. nummifer or S.congica. These are usually then all sold as notata. S. notata is more active during the day than many Syno species and therefore makes a good addition to aquariums with more boisterous...
