Blue early-tail guppy

Origin and distribution: Venezuela, Guyana, the West Indies, and the islands

Morphological characteristics:

The male fish's front half to rear half is evenly covered with gold or silver scales # those that emit yellow light are also platinum. Platinum is a very active dominant gene # it often recombines onto the female fish, and then recombines again

resulting in a situation where two recessive genes are simultaneously expressed in one male fish. The body color is even more vivid than that of the blue tail tuxedo, and it also carries a platinum glow.

Purchasing key points

The blue waist paired with the blue grass tail is indeed very beautiful. If its genes are one dominant and one recessive # the offspring will definitely produce red grass tails.

Food types

Can be fed tubifex worms, water fleas, and artificial synthetic bait

material.

Mixed-culture index

Can be kept together with small fish of the same body shape and temperament.

Rearing adaptability index

It is a relatively easy fish to keep # suitable for beginners to raise.

Breeding method

At 4-5 months of age the gonads mature # but the reproductive capacity is very weak. In water at a temperature of 241 # and around the appropriate hardness # it can breed once a month # the number of fry produced each time varies with the size of the fish # at least 10 or more # at most

70-80 fry. When the female's abdomen swells and bulges out # and an obvious black gravid spot appears near the anus, these are signs that she is about to give birth. When breeding blue grass guppies, choose a relatively large aquarium # keep the water temperature at

26 with a [^ value of 6.8-7.4 ^ at the same time plant more aquatic plants # then place the breeding fish in at a ratio of 1 male to 4 females. After the fish become aroused, the female's abdomen gradually swells # and a black gravid spot appears; the male at this time

continuously chases the female # when the male's gonopodium is inserted into the female's cloaca, sperm is released # and internal fertilization takes place. When the female's gravid spot becomes large and black, and the anus protrudes, she can be transferred to another aquarium

to await birth.

After the female gives birth to the fry # she must be removed immediately # to avoid eating the fry. Or use a plastic sheet to form a funnel-shaped isolation wall # immerse it in the water, place the birthing female in the funnel # so that after the fry are born they pass through the hole at the bottom of the funnel

into the water outside the funnel # and the female cannot eat the fry.

Rearing method

Gentle in temperament # lively and active # can be kept together with other tropical fish. Guppies are easy to keep # but to obtain fish with vivid body colors and graceful body shapes, from the fry stage they need a spacious water body and more aquatic plants #

live bait # suitable water quality and other conditions. In a narrow area, territorial disputes may occur # and in severe cases it can lead to fish death # so when the space is small, it is suitable to keep a single fish.

Water changes and cleaning

Blue grass tail guppies have relatively strict requirements for water quality # during rearing the water temperature is usually kept at 20^-321 ^ and water changes are required twice a week.

Water quality environment

The most suitable growth temperature is 221-241 ^ it prefers slightly alkaline water # with a value of 7.2-7.4.
