Snails in the freshwater aquarium
Snails play an aquarium an especial andimportant role. Already our grandfathers, compelled to be satisfied with the maintenance of is cold-water fishes, considered snails as " sanitaryinspection ", exterminating seaweed, and also processing the excessiverests of a forage. Besides they eat corpses of fishes and thus watch that in anaquarium poisonous substances did not accumulate. For the maintenance inхолодноводных aquariums, besides the red horn coil (Planorbis comeus), however,it is fine themselves feeling and in warm water, Bulimus tentaculus in the size10-12 mm,and also 35-millimetric Viviparus viviparus very approach.
Beforeyou occupy these molluscs in an aquarium, long time is necessary (about 6weeks) to observe them in the separate tank: very often they bear in themselvespathogenic microbes which are transferred fishes. Warm-water into sfera ofaquarium horn coils are known first of all. In most cases to occupy them in anaquarium it is not necessary, in one fine day they there appear. Despite ofквасцовую a tray for plants, despite of all other safety measures, theseessences find ways of penetration to our aquariums and duplication inside ofthem. Until then while the quantity of their cockleshells does not passborders, they cannot bring harm. But if as a result of any specialcircumstances their mass duplication has put already worse begins. More often aquariumman struggles with invasion itself, collecting larger copies from a bottom andfrom plants and deleting them from an aquarium.
Fineer snails can be crushedsimply, having pressed to glass, - and fishes will clean the rests. Indiansandy (Melanoides tuberculata) the whole days ploughs an aquarian bottom, than.Certainly, benefits plants. These viviparous snails cannot live in too softwater because to them it is necessary известь for formation of cockleshells.But to be made multiple copies they begin already at 4 - 6 degrees of rigidity.It basically concerns and to the majority of other kinds. These molluscsreaching at length about 25 mm,can live at temperature of water not below 20 ° S.Gigantami among aquariansnails different kinds ampullaris are considered. The relative open space thatis why in small aquariums to contain them is necessary to them is notnecessary. These snails with the great pleasure devour a forage intended forfishes. However, moving with speed of a snail, they not always have time toreach the power supply so are cleaned with what in time.

At feeding tube they often guard occurrencepeep directly under percolator oron that place where the alive forage falls. Snails exhaust a forage from aground. As devourers of seaweed they will not miss a delicacy and at feeding bysalad. In the shortest term they are capable to destroy the big salad leaf. Ifyou want to observe it press down a leaf of salad small stone (preliminary having washed up it withall carefulness) and lower on a bottom. It is possible to make out in detailshow the snail tears off a mouth a slice behind a slice and eats. Feature ampullarismakes "trunk" which they extend when sit in water not better qualityand wish to inhale atmospheric air. When the snail does not use it, it isinvolved and becomes absolutely imperceptible. In case of danger the snail canhide entirely in the small house and close an aperture a cover.
This kind of amollusc too can be made multiple copies in a house reservoir. ampullarispostpone caviar on that place of aquarian glass where it water does not concernmore often. From caviar of this southern American guests after a while there isa set small snail. The majority aquarium mans is pleased to occurrence of this younger, and many zоо dealers immediately buy up atall of them "livestock". Pond use bad glory as devourers of plants.More often them bring in an aquarium together with a forage caught in stagnantwater. Pond ordinary (Lymnaea stagnalis) - most known of wreckers. If it willlodge in an aquarium, will get rid of it very difficultly. Many kinds of snailsare made multiple copies more quickly, than it it would be desirable the ownerof fishes and plants. The most different means of struggle have been approvedwith greater or smaller success. Radical influence is rendered with variouschemical means, but only they destroy all snails at once. Not less effectiveway - to start in an aquarium a fish from family of four-tooths. The one whohas settled all means, can try and it, having taken one of two small kinds ofthe named family: it Tatraodon steindachneri or fluviatilis. (But in that caseit is necessary to remove in advance from an aquarium ampullaris if you do notwish to lose at the same time and them.) the fishes devouring snails, will veryquickly consult with the problem so in an aquarium there will be one onlycockleshells.
