Harlequin rasbora

The harlequin rasbora may be a fish that has associate or so lozenge-shaped body, whose basal color from the pinnacle to the caudal peduncle is associate orange-pink, the precise hue variable relying upon such factors as water conditions and therefore the original population from that the fish was obtained. The posterior 1/2 the body is overlaid with an outsized, roughly triangular black marking, that tapers toward the terminal finish of the caudal peduncle, and begins or so below the centre of the attachment of the fin (commonly referred to as a "black wedge"). In common with all cyprinids, the articulation of the pectoral and girdle fins follows a well-recognized pattern, the pectoral fins being placed at once posterior to the plate or gill cowl, while the girdle fins area unit placed how additional back on the ventral portion of the body, during this case virtually directly in an exceedingly vertical line drawn through the fin. This relationship between the pectoral and girdle fins is seen in characins also as cyprinids, associated may be a feature of all the ostariophysans (fishes possessing an auxiliary mechanism for police work sound consisting of a collection of internal bones referred to as the Weberian ossicles).
The dorsal, anal, caudal and girdle fins area unit all tinted red, the fin being forked, with the red color targeted within the outer rays, the inner section of the tail fin being additional hyaline.

It is attainable to confuse this fish with 2 similar species that were so originally thought of to be taxonomic group of T. heteromorpha, specifically Trigonostigma espei and Trigonostigma hengeli. These fishes area unit additional slender in body form than T. heteromorpha, and therefore the black marking, rather than being or so triangular, includes a horizontal stripe that tapers towards the caudal peduncle, and is greatly thickened and extended downwardly below the fin. thanks to this fishes with this marking area unit unremarkably called "lamb chop rasboras" thanks to its perceived likeness to the butchery cut called a lamb chop.
A fully mature individual harlequin rasbora attains a regular length of 2 inches (5 cm).
Males area unit cited as possessing a rather larger black body patch than females, with the section abutting the anal fin being additional rounded in males. Ripe females area unit perceptibly fuller in body define.

Guppy

Guppies exhibit sexual dimorphism. whereas wild-type females ar gray in body color, males have splashes, spots, or stripes that may be any of a good sort of colours the scale of guppies vary, however males ar generally one.5–3.5 cm (0.6–1.4 in) long, whereas females ar 3–6 cm (1.2–2.4 in) long.
A variety of Lebistes reticulatus strains ar created by breeders through selective breeding, characterised by completely different colors, patterns, shapes, and sizes of fins, like snakeskin and grass varieties. several domestic strains have morphological traits that ar terribly distinct from the wild-type antecedents. Males and females of the many domestic strains typically have larger body size and ar rather more lavishly ornate than their wild-type antecedents
Guppies have twenty three pairs of chromosomes, as well as one try of sex chromosomes, constant variety as humans The genes answerable for male guppies' ornamentations ar Y-chromosome connected and ar inheritable
Guppies like a tough water fish tank with a temperature between twenty five.5 and 27.8 °C (78 and eight2 °F) and salt levels adore one tablespoon per nineteen l (5 USA gal) they'll stand up to levels of salinity up to one hundred and fiftieth that of traditional water,[49] that has light-emitting diode to them being often enclosed in marine tropical community tanks, also as in fresh tropical tanks. Guppies ar typically peaceful, although nipping behaviour is usually exhibited between male guppies or towards different prime swimmers like members of the Xiphophorus genus (platies and swordtails), and infrequently different fish with outstanding fins, like angelfish. Guppies mustn't be unbroken as one fish in associate fish tank as a result of each males and females show signs of shoaling, and ar typically found in giant teams within the wild. Its most known characteristic is its propensity for breeding, and it will breed in each fresh and marine aquaria.
Guppies like water temperatures around twenty two.2–26.1 °C (72–79 °F) for replica. Pregnant feminine guppies have enlarged and darkened big spots close to their anal vents. simply before birth, the eyes of fry could also be seen through the clear skin during this space of the female's body. once birth happens, individual offspring ar born in sequence, generally over a amount of 1 to 6 hours. the feminine Lebistes reticulatus has drops of 2 to two hundred fry at a time, generally go between thirty and sixty.
Well-fed adults don't usually eat their own young, though typically safe zones ar needed for the fry. Specially designed livebearer organic process tanks, which might be suspended within the fish tank, ar on the market from aquatic retailers. These conjointly serve to protect the pregnant feminine from additional attention from the males, that is vital as a result of the males typically attack the females whereas they're giving birt. It conjointly provides a separate space for the newborn young as protection from being consumed by their mother. However, if a feminine is place within the stockman box too early, it should cause her to possess a miscarriage. Well-planted tanks that supply barriers to adult guppies shelter the young quite well. Lebistes reticulatus grass, water faerie, water vine, duckweed, and java nonvascular plant ar all smart selections. endless offer of live food, like water flea or Artemia salina, keep adult fish full and will spare the fry after they ar born. Young fry take roughly 3 or four months to succeed in maturity. Feeding fry live foods, like baby Artemia salina, microworms, class and vinegar eels, is usually recommended. Alternatives embody finely ground flake food, egg yolk, and liquid fish food, although the particulates in these could also be overlarge for the youngest fry to eat.

Gold barb

Adults of this species have extremely arched backs and a brief combine of barbels on the upper jawbone at the corners of the mouth. the rear is light-weight to Venetian red, the edges square measure gilded inexperienced or chromatic, with a brassy or golden radiancy below. The belly is whitish, turning orange-red in males at sex time. Females is distinguished by their uninteresting colours and their overall bulk.
This species will reach a length of seven centimetres (2.8 in) thallium tho' most don't exceed three.5 centimetres (1.4 in) SL
Their diet consists of invertebrates (such as insects, crustaceans and worms) and plant matter.
An egg-scatter, adult barbs can typically spawn around 100 eggs, though up to four hundred eggs are determined from Associate in Nursing exceptional feminine. This breeding happens at the primary light-weight within the early morning.
The popular gold strain P. semifasciolatus power unit. composeri (gold barb or Schuberti barb) was developed by amateur Thomas Schubert of metropolis, New Jersey within the Nineteen Sixties through selective breeding. for several years it absolutely was thought to be a definite species however is in truth a particular kind of the autochthonous (green) species that is never found in aquaria. The gold barb is an energetic, gently aggressive schooling species that spends most of its time within the mid-level and bottom of the water. Its typical time period in captivity is around four to 6 years. This gold fish is commonly employed in community tanks by fish keeping hobbyists. It breeds promptly in out of doors pools and free-standing ponds throughout summer months, and withstands cooler temperatures higher than alternative tropical fish. However, it doesn't stand the cold similarly as its original plainer China barb counterparts.
Albino variants of the daring barbs are created by Dennis Wilcox within the Nineteen Seventies within the America. Gold barbs with no black markings are determined by Stanislav Frank in Europe additionally around that point. Flesh color (pink) specimens appeared by the Nineties. Tri-colour, i.e., black, orange and pink specimens appeared recently.
