Girardinus metallicus

Girardinus metallicus, scientific name Girardinus metallicus, belongs to the Poeciliidae family. Once (at the beginning of the XNUMXth century) a fish quite popular in the aquarium trade, due to its incredible endurance and unpretentiousness. Currently, it is not often found, largely due to its unprepossessing appearance, and then mainly as a source of live food for other predatory fish.

Habitat

It comes from the islands of the Caribbean, in particular, wild populations are found in Cuba and Costa Rica. Fish live in stagnant water bodies (ponds, lakes), often in brackish conditions, as well as in small rivers and ditches.

Deskribapena

In adults, sexual dimorphism is clearly expressed. Females are significant and reach 7 cm, while males rarely exceed 4 cm. The color is gray with a silvery belly, fins and tail are transparent, in males the lower part of the body is black.

Mantentzea eta zaintzea, akuarioaren antolaketa

The minimum recommended aquarium volume for a Girardinus group starts at 40 liters. The decoration is arbitrary, however, in order for the fish to feel most comfortable, dense clusters of floating and rooting plants should be used.

Water conditions have a wide acceptable range of pH and GH values, so there are no problems with water treatment during aquarium maintenance. It is allowed to keep in brackish conditions at concentrations not exceeding 5 g of salt per 1 liter of water.

Portaera eta bateragarritasuna

Exceptionally peaceful and calm fish, perfectly combined with other species of similar size and temperament, and due to the ability to live in various water conditions, the number of possible neighbors increases many times over.

Hazkuntza / hazkuntza

Girardinus metallicus belongs to the representatives of viviparous species, that is, the fish do not lay eggs, but give birth to fully formed offspring, the entire incubation period takes place in the body of the female. Under favorable conditions, fry (up to 50 at a time) can appear every 3 weeks. Parental instincts are poorly developed, so adult fish can eat their own brood. It is recommended that the fry that appear be transplanted into a separate tank with identical water conditions.

Arrainen gaixotasunak

Osasun-arazoak lesioen kasuan edo baldintza desegokietan mantentzen direnean bakarrik sortzen dira, eta horrek sistema immunologikoa deprimitzen du eta, ondorioz, edozein gaixotasun agertzea eragiten du. Lehen sintomak agertuz gero, lehenik eta behin, beharrezkoa da ura zenbait adierazleren gehiegikeria edo substantzia toxikoen (nitritoak, nitratoak, amonioa, etab.) kontzentrazio arriskutsuak egotea. Desbideraketak aurkitzen badira, itzuli balio guztiak normaltasunera eta gero bakarrik jarraitu tratamenduarekin.
