Hasemía

The copper tetra or Hasemania, scientific name Hasemania nana, belongs to the Characidae family. It is considered one of the best Tetras for the general aquarium due to its bright coloration, excellent compatibility with other popular fish, hardiness and unpretentiousness.

Habitat

It comes from the San Francisco River basin (port. Rio São Francisco) from the territory of Brazil. It occurs in small streams, rivers and channels of the main channel. The habitat experiences seasonal fluctuations in water levels, and the river itself flows through hilly, in places mountainous terrain.

Lýsing

Adults reach a length of about 5 cm. The color is silvery with a rich copper tint. Most of the caudal peduncle is dark, the tips of the tail and fins are white. Females are more modestly colored, the colors are not so saturated.

Matur

Absolutely not pretentious appearance, the walls accept all types of popular food (dry, frozen, live). Their quality and composition largely affect the color of the fish, so strive to purchase food only from well-known and reputable manufacturers.

Viðhald og umhirða, fyrirkomulag fiskabúrsins

For a group of fish of 8-10 individuals, a tank of 70 liters or more will be required. Hasemania is not demanding in the design of the aquarium and adapts perfectly to various water conditions. The only recommendation is the presence of subdued lighting, because in bright light the color of the fish noticeably fades, becomes nondescript.

Hegðun og eindrægni

A peaceful schooling fish, kept in a group of at least 8–10 individuals, with a smaller number become somewhat aggressive, although with their size it is unlikely that they will be able to cause problems to their neighbors. Compatible with many well-known aquarium species, including viviparous, zebrafish, rasboras, corydoras catfish, some gourami, South American cichlids and others.

Ræktun / ræktun

Útlit seiða er mögulegt jafnvel í algengu fiskabúr, en fjöldi þeirra verður mjög lítill og mun minnka á hverjum degi ef þau eru ekki ígrædd í sérstakan tank í tíma. Allt er þetta fullorðnum fiski að kenna, þar sem seiði eru frábær viðbót við fæðuna.

In order to increase the chances of survival and somehow systematize the breeding process (spawning was not spontaneous), it is recommended to use a spawning aquarium, where sexually mature fish are placed during the mating season. Usually this is a small container with a volume of about 20 liters. The design is arbitrary, the main emphasis is on the substrate. In order to protect the eggs from being eaten (Tetra copper eats its own offspring), the bottom is covered with a fine-mesh net, or small-leaved plants or mosses (for example, Java moss). An alternative way is to place a layer of glass beads with a diameter of at least 1 cm. The lighting is subdued, a heater and a simple airlift filter are sufficient from the equipment.

Hvatinn fyrir upphaf mökunartímabilsins er smám saman breyting á vatnsbreytum í almenna fiskabúrinu í eftirfarandi gildi: pH 6.0–6.5, dH 5–10 við um 28–30°C hita. Grunnur mataræðisins ætti að vera frosinn eða lifandi matur.

Fylgstu vel með fiskunum, fljótlega munu sumir þeirra áberandi rúlla upp - þetta verða kvendýr sem eru bólgin af kavíar. Karldýr munu byrja að gefa frá sér hljóð sem líkjast croaking - þetta er eiginleiki þessarar tegundar og sýnir merki um athygli á útvöldu. Undirbúðu og fylltu hrygningartankinn með vatni úr samfélagstankinum. Settu kvendýrin þar, daginn eftir nokkra stóra karldýr sem líta mest áberandi út.

It remains to wait until spawning occurs, its end can be determined by females, they will “lose weight” greatly, and eggs will be noticeable among the vegetation (under a fine mesh). The fish are returned. The fry will appear within 24-36 hours, after another couple of days they will begin to swim freely in search of food. Feed with specialized microfeed.

Fisksjúkdómar

Jafnt lífkerfi fyrir fiskabúr með viðeigandi skilyrðum er besta tryggingin gegn tilviki hvers kyns sjúkdóma, þess vegna, ef fiskurinn hefur breytt hegðun, litur, óvenjulegir blettir og önnur einkenni koma fram, athugaðu fyrst vatnsbreyturnar og farðu síðan í meðferð.
