    Expert Answer
    Acclimating aquatic snails to a new tank involves a water transfer method similar to that used for fish. If the snails arrive in bags, start by removing about half of the water and replacing it with display tank water every 10 minutes, repeating this process three or four times. This gradual transition helps the snails adjust to the new tank conditions. Once in the tank, ensure there are no predatory fish that may harm them. If the tank has algae on the rocks, the snails can feed on it as a natural food source. In the absence of algae, consider providing supplemental feed to sustain the snails.

    For effective algae control in aquariums, consider employing tropic snails, as they excel at managing algae growth. Another excellent option is turbo snails, known for their proficient algae-cleaning capabilities. These snail varieties can be vital in maintaining a balanced and algae-free aquatic environment.

  • Question
    My snail is barely moving and staying on the bottom of the fish tank. Is he sick? What can I do?
    Community Answer
    Water snails sometimes hibernate so don't worry, maybe it will take a few weeks or even months to awaken again. However, if it's a land snail, spray it with water and if it doesn't move after a few days, it's dead.

    How often do mystery snails need to eat? I heard they need a source of calcium for their shells - is this true?

    Mystery snails need to eat as much as they can consume in 1 to 3 minutes, twice daily. They do need calcium for healthy shells. You can give them a calcium supplement or simply use hard water so that their calcium needs are met.
  • Question
    How many sea snails can be in a tank at once? I have about 20 of them, and I was wondering if they can be in a tank together.
    Community Answer
    It depends on the size of your tank. Do not exceed 20 snails per gallon of water.
  • Question
    Can I leave my snails in the tank when changing the water?
    Community Answer
    Yes. I did it quite frequently. Some snails are more sensitive though, so double check how hardy your snails are. Malaysian trumpets are so hardy that they can survive out of water for 3 days or so, survive in freezing cold water for a week, boiling water for a good few hours, and can even survive a bleach bath.

  • Question
    Is a filtration system needed for a snail tank?
    Community Answer
    A filtration system is optional for snails. If you don't have a filtration system, you should change out about 20% of the tank water every 4-5 days. When you change the water, make sure you are using water treated with non-copper based aquarium conditioner or a similar product.This has worked successfully for stream snails.

    Snails shells start breaking apart because there is not enough calcium in the water. Try adding cuttlebone or eggshells for more calcium.
  • Question
    I have got my snail from the pet store and it has not moved, should I be worried?
    Caeiia
    Top Answerer
    It is probably getting used to its environment, as it has just been moved to an entirely new place. It will slowly move out of its shell, but if it doesn't in a few days, pick it up and smell it. Yes, that is odd, but a dead snail will smell horrible. Don't continually poke or bother the snail, though.
