Snails don’t like York tapwater: use standard snail water
York tapwater is lethal to Lymnaea stagnalis snails, so use the standard snail water using this recipe. It is a good idea to change the water twice a week
Always Replace the water if:
Snails do like lettuce
Wash it carefully and shake off the loose water droplets (Don’t get the floor wet!). They prefer the flat leaves; and don’t like the heart of the lettuce (or iceberg lettuces).
Snails don't like to be overcrowded!
Don't try to keep more than 20 snails in each of my tanks - they will die quickly if they are overcrowded.
Sometimes snails bought in from Blades have a lot of little internal parasites. These will go if the water is changed regularly. You should use latex gloves to handle the snails while the snails are heavily parasitised.
