Xiphophorus multilineatus<\/em> is one of nine\nnorthern swordtails and belongs to the Pygmaeus clade consisting of consisting of X. pygmaeus<\/em>, X. nigrensis<\/em> and X. multilineatus<\/em>.<\/p>\n\n\n\n

Type\nLocality:<\/strong><\/p>\n\n\n\n

Rio Coy near its confluence with the Rio\nTampaon, Rio P’anuco drainage, SLP, Mexico.<\/p>\n\n\n\n

Distribution:<\/strong><\/p>\n\n\n\n

Rio Coy system, Rio Panuco drainage, SLP:\nthroughout Rio Coy, Arroyo Tambaque, and Arroyo Oxitipa as far as Octzen.<\/p>\n\n\n\n

Habitat:<\/strong><\/p>\n\n\n\n

Found\nin a fast flowing river with dense aquatic plant growth\nand overhanging shore\nvegetation.<\/p>\n\n\n\n

Size:<\/strong><\/p>\n\n\n\n

Males: 25mm to 40mm,     Females: 40mm <\/p>\n\n\n\n

Distinguishing\ncharacteristics:<\/strong><\/p>\n\n\n\n

A species with a four known size variations\nwithin the male range, the largest variant is the one most often in the hobby. X.\nmultilineatus in its larger form is a small high backed form of swordtail with\na medium sized sword of roughly \u00bd – \u00be total body length.<\/p>\n\n\n\n

Colour\/Pattern\nVariability:<\/strong><\/p>\n\n\n\n

Males<\/p>\n\n\n\n

There are four size variants ranging from\n25mm to 40mm, the larger males develop a high back and vertical barring on the\nflanks. All males have a body colouring of pale metallic blue and a single bold\nzigzag midlateral line, (present from birth). A black spot can be found at the base\nof the pectoral fins on all sizes of male except the smallest size variant. The\nscales above the lateral have a dark edge giving a net like appearance.<\/p>\n\n\n\n

A caudal\nspot is present but only really prominent on the large males. The caudal fin is\nedged in black and has is generally clear. The sword length varies according to the size variant, the largest males\ncan have a sword length equal to the body length and the smallest 1-2mm. The\nsword is distinctly upturned, particularly when small and the colouring does\nnot reach the end of the sword, the sword is edged in black.<\/p>\n\n\n\n

The\ndorsal fin is generally clear, there is a black edge and a black band one third\nof the way up the fin.<\/p>\n\n\n\n

As\nwith all of the Pygmaeus clade a yellow male form can be found, but in X.\nmultilineatus this only exists in the smaller size.<\/p>\n\n\n\n

Females<\/p>\n\n\n\n

A basic\nbody colour of greyish blue with a single bold zigzag lateral line. The scales above the lateral have a dark edge giving a net like\nappearance.<\/p>\n\n\n\n

The\ndorsal fin is clear, there is a faint black edge and faint black band one third\nof the way up the fin.<\/p>\n\n\n\n

Behaviour:<\/strong><\/p>\n\n\n\n

A timid species that spends much of its\ntime hidden amongst the foliage.<\/p>\n\n\n\n

Husbandry:<\/strong><\/p>\n\n\n\n

A large well planted with filtration,\naeration and frequent water changes.<\/p>\n\n\n\n

Breeding\nNotes:<\/strong><\/p>\n\n\n\n

Broods are born on a monthly cycle and\nnumber about 5 \u2013 10, 20 being generally the maximum amount, fry are large and\nnormally left alone by the parents.<\/p>\n\n\n\n
