The snail will still grow even though it lives in an aquarium, so yes the snail will out grow it's current shell and need a new one.
The shell of a snail protects it from predators.
Calcium carbonate.
When it perceives a need for protection.
You are the snail and the shell symbolizes your "armour," your psychological defenses against emotional wounds. The dream illustrates your feeling that you need more protection.
I have discovered snail trails eaten into a degraded concrete pathway around a millimetre or so deep. I can only presume that by doing this, they aquire calcium for their shell.
The only way I know of is to strip down the tank, sterilise everything and replace everything that can not be sterilised. A method of keeping snails under control is to have Clown Loaches or Puffer fish in the tank. They will seek out and eat the snails.
Snails usually eat the algae in the tank which is why they are so useful for keeping it clean. If your tank does not have enough algae and other matter for them to eat they will die. Special food is available for tank snails and they also eat fish food.
Snails do not shed their shell their shell is apart of their body. A snail shell will grow with the snail. I currently have 3 snails but in spring i hope they breed! I know they dont need to mate but the type i have do.. ;) i hope i helped good luck if u have a snail... ;)
All snails are neither male / female. they have both gender organs.
Once you have snails infesting your fish tank you will find it very difficult to get rid of them. They seem to live no matter how hard you try to kill them.
No
Yes,snails can have a family and the snail don't need to mate with another snail
