Orange rabbit snail
Orange rabbit snail (kumquat rabbit snail), scientific name tylomelania zemis, English name orange rabbit snail, is a large snail of the genus Tylomelania, because of its appearance like a rabbit is very cute, so it is also called rabbit snail. The requirements for the acidity and alkalinity of water quality are about 7.2 to 8.6 pH, the requirements for the hardness of the water body are about 5 to 10 dkh, and the requirements for the temperature of the water body are about 18 to 35 °C, and the low temperature is not suitable for its growth. In general, the hand is slow about 2 to 3 years, the lifespan of a healthy orange rabbit snail is at least 5 years, and the adult size is about 6-8 cm. Orange rabbit snails have no strict requirements for food, and the range of food is more varied, including algae sedimentary feed; It also eats rotting plants and the young shoots of certain aquatic plants. The tylomelania zemis has a lovely and peculiar color, and this orange snail is collected in Lake Poso in Sulawesi and requires a higher water temperature.

Habitat
The dream island of Sulawesi, Indonesia, in addition to a variety of fish and shrimp. Curloids of the genus Tylomelania have also been found and observed in their habitats. When I studied the limited scientific literature, I found that almost no research had been done on the genus, which undoubtedly opened up a huge field for those molluscs.
Aquarium enthusiasts also learned of the existence of this snail in 2007/2008, when Sulawesi shrimp swept the world. In addition to the caridina, which has a peculiar color, various snails with beautiful shells and attractive soft parts of the color also dramatically enter our aquarium.
After a slow but steady spread of water quality information about the shrimp's need for high temperatures, weak alkalinity, and medium hardness, it is natural to assume that these snails from the great lakes of central Sulawesi also need a very warm environment. However, as we know so far, only some of them are correct, and these tylometania snails are found throughout much of Sulawesi, and they live not only in high-altitude lakes and rivers, but also in the low-lying valleys and large rivers of the lowlands, so it is completely wrong to generalize them. Unfortunately, the different ecological types are difficult for non-specialists to distinguish from their appearance, so how to introduce these rabbit snails will allow people to decide which breed they want to buy and how to take care of them after reading this article. First, I will explain the biology of these fascinating species and the basic captive rearing methods, and then cover the various communities and habitats.
Living habits and breeding
Orange rabbit snails belong to the pachychilidae family. The primitive form of the modern Pachycephalus family must have existed during the gondwana supercontinent period, as its extant species inhabited those areas of its past (Central and South America, the African continent, Madagascar and Australia) and are ancient remains.
The orange rabbit snail is much more lively than the starry snail, and prefers to walk in the aquarium; Sometimes I also like to bury my head under the bottom sand, eat the organic debris at the bottom to activate the bottom sand (and Su shrimp polyculture needs to pay attention to, adult orange rabbit is lanxiang graduate excavator. Too many shrimp may affect the shrimp, it is recommended to use orange rabbit baby or full of stars. )
The orange rabbit snail will soon start breeding as long as it is guaranteed sufficient food. Unlike other species of Sulawesi snails, orange rabbit snails do not like to eat live plants, and they will look for food in glass, sunken wood, sand, dead aquatic weeds, and fish-eating bait. The feeding habit of orange rabbit snail is relatively mixed, and it can be used for algae removal in aquariums; Orange rabbit snail is a good cleaner in the aquatic weed tank, and will also eat some spirulina feed, spinach leaves, lettuce foods to supplement its calcium, and can also eat sedimentary feed, residue in the aquarium, pumpkin carrots and so on. But more love meaty food. When there is a sedimentary feed and fish and shrimp carcasses, they will not hesitate to put down the algae in front of them and eat delicious meat. Therefore, when raising orange rabbit snails, we should pay more attention to maintaining the diversity of feed, and orange rabbit snails will grow healthily.
It is recommended to raise high-grade sinking bottom feed + vegetables as water pets rather than as tool creatures.
Water quality and temperature: the orange rabbit snail of the fixed water is quite adaptable, and it is possible to use tap water in addition to chlorine and toxic substances in tap water, or to use ro water + Hegen is no problem at all. The recommended temperature is 25-26 (the temperature at which it can be propagated and compatible with the temperature of cold-water snail polyculture of some varieties)
reproduction
The genus tylomelania belongs to the pachychilidae family, and its members are found in large tropical regions. "Thick-lipped" (from the Greek, pachy = thick, chilus = lips) snails get their name from the fact that the edges of their shells often become very thick. There are other species belonging to this family that are also well known to aquarium enthusiasts, such as faunus (black curl) and a large number of brotia (sichuan curl snail) species.
Tail weathering: Most of the snails bought on the market are wild snails that will weather the tail, and ordinary people can't keep the so-called "whole product" wild environment weathered even if they start from the snail baby. The end of the small snail tail turns whiter as it grows larger. The good news is that tail weathering, the so-called "tail shear", does not affect snail breeding.
Even if it is really called tail shearing, it does not affect reproduction: a quarter of the recorded tail defects of the snail shell still give birth to snail babies (the key factors for reproduction are good nutrient intake and suitable and stable environment)
Whole product retention: regular supplementation of high-calcium and high-protein foods, creating a good environment to maintain good water quality and adding appropriate gh additives such as Hegen, etc.
They are only suitable for living in aquariums under certain conditions, because their breeding methods are very special.
Rabbit snails are endemic to Sulawesi and have developed a very special breeding strategy:
They are oviparous, and each offspring is wrapped in an oocyst that relies on secretions from the mother's womb for nutrition. By the time the snails hatch from the eggs, they have developed and even their shells have become very hard. Some larvae of rabbit snails are able to grow to nearly 2 centimeters in length in the mother, which is a record of snails.
Immediately after the birth of a baby rabbit snail, another egg is released from the fallopian tubes into the womb, probably because the environment of their tropical habitat changes little. There are no four seasons, so there are no external factors that affect their successful reproduction. Therefore, when raising them in aquariums, a stable environmental condition is crucial.
The orange rabbit snail generally lays one snail egg, and the highest record is three. Depending on the size and condition of the conch, the size of the baby born varies from 3 mm to 1.5 cm.
Snail baby grows to be able to reproduce the size of 4cm as an example, at least 8 to 12 months, careful feeding, nutrition can shorten the cycle to a certain extent.
Wild snail water repellent
The reasons why the water loss of wild snails is increasing year by year are unknown, which may be due to defects in the packaging of Indonesian fisheries. Special attention should be paid when crossing the water.
You can refer to the gradual method of crossing the water of the shrimp, and the speed is not reached.
Wild snails generally have a small red parasite that can be repelled by soaking in brine for a few minutes (a small spoonful of iodized salt mixed with 300ml of water) in a safe dose, or by using British large white tablets.
Sulawesi snails are independent breeds: tylomelania belongs to the pachychilidae family and does not have schistosomiasis without nail snails.
Population status
Although the number of imports has been relatively stable in recent years, it has become green and yellow, and the individuals of wild snails imported are getting smaller and smaller. Slow growth rates and overfishing certainly affect stock sizes.
Fortunately, the number of populations in the hands of players in various countries is stable, the difficulty of feeding is also introductory, and the population can be sustainable.
