Snails are crawling creatures that live in fresh water, the sea, and on land. Their structure is such that they have a protective shell over their body. Whenever they feel any danger, they go inside this shell. More than 40000 species of these are found. They are mostly herbivorous and eat algae, leaves, fungi, and other plant matter. Up to 20000 small teeth are kept in their mouth. The body of snails is soft, has a sieve, has muscular feet, and has eye stalks. They secrete slime ( mucus ) to avoid dehydration and to move around . Their shell is made of calcium carbonate, which grows with their body and forms a spiritual house for it. Mostly, they are herbivores and eat algae, fungi, and plants, although some are carnivorous. They use a radula to chew food . They have 12,000 to 14,000 teeth in their mouths. They mostly live in wet places, forests, and gardens. Most species live for 3 to 7 years, but some species can live for more than 20 years. Most snails are hermaphrodites, having both male and female organs, but still need a partner to lay eggs. They hibernate during winter and summer, often sealing their shell with a hard mucus layer to prevent drying. Snails, particularly Helix pomatia snails or Helix aspers snails, are eaten like escargot. It is low in fat and high in protein and vitamins.

Advantages and disadvantages of snails in tanks :

Keeping snails in the tank is a very important matter; some people think it is good, and others do not. Their benefits and disadvantages are that they eat leftover food from the tank, eat algae, and keep the tank clean. They supply oxygen to the soil and remove poisonous gases.

Some fish also eat snails and are good for their food.
Disadvantages:
Some types of snails multiply rapidly, filling the tank with snails.
They eat dead plants, but some species will also eat live plants when they are very hungry.
Too many snails lead to excessive waste, which increases ammonia nitrate instead of ammonia nitrite, which is very harmful to the fish.
Once they enter the tank, they are difficult to kill quickly.
These eggs are deposited everywhere in the tank and are easily visible in the water.
But some snail types cause less harm and more benefit, such as nerite snails, which do not lay eggs in freshwater and are good cleaners. Mystery snails are algae eaters, and their eggs are deposited outside the water, so their population can be controlled.

They clean by eating fish waste, leftover food, and dead plants. Do not keep snails with poisonous fish, as they can harm the snails. If the snail is very small, then the fish can eat them.

Snails can be controlled by cleaning them and not by spraying too much food or by destroying their eggs on the glass vessel.
