vegetables

most people think you can just give your snail some lettuce and call that a day. that is not the case.
veggies and fruits take up for about 70 precent of a recommended, healthy diet for a regular garden or land snail.
around 60% of said snail's diet should be made of veggies, and the other 10% of fruits.

fruits
only 10% of a healthy diet for snails is made of fruits. if you feed your snail(s) too much sugar, it could lead to diseases and deformities. please limit yourself to only feeding fruit as a treat and not more than a small portion once a week. some tend to like more sweet fruits than the others, so make sure to portion size for them. some recommended fruits (make sure to only feed the fruit, not the plant or leaves unless stated otherwise.) are:
Apple (not seeds)
Apricot (not seed)
Banana
Bilberry
Black Berries
Black Currant
Blueberries
Cherry
Coconut
Cranberry
Dragon Fruit
Grapes (Not Grape Ivys) Leaves, Fruit
Kiwi
Mango
Melon / Cantaloupe
Nectarine (not seed)
Passion Fruit
Peach (not seed)
Pears (not seeds)
Plantains
Plum (not seeds)
Pomegranate
Quince
Raisins
Raspberry
Sharon Fruit
Strawberry
Water Melon

calcium
around 15 to 30 precent of a healthy diet for snails is made of calcium. calcium is extremely important, as they need it to grow and keep their shell healthy. snails should be given a constant supply of calcium in their enclousre.
there are a few different methods to supply your snail(s) with calcium, but this is my favorite:
cuttlefish bone

cuttlefish bone or cuttlebone is a hard, white shell. its not really a bone nor does it come from a fish, actually. its just a shell found in all members of cuttlefish which is a creature similar to a squid or an octopus.




for small snails and hatchlings it is recommended to split the cuttlebone and place it in different areas of the encolusre. if it gets too dirty, wash it in water.

although this method is the majority's favorite, if you do not like it, that is okay. i decided to not list any other methods simply because i do not know enough about them to confidently mark it as correct, true and recommended information. sorry!! you can research about it though :( p.s. unless your snails are not getting their calcium, it is recommended not to sprinkle calcium on food (see "calcium powder" below). snails know when to eat calcium, if they need to. kinda like how you drink water when you are thirsty, so usually there is no need to worry about it. forcing them into eating calcium may cause their shell harm.

calcium powder

you can also sprinkle calcium on your snails' food if your snails are for some reasons avoiding the cuttlebone ! you can also just feed them calcium high food !

egg shells

remove the inside skin , and wash the eggs ! if you wish to crush it , you may find baking the shell in the oven makes it more brittle ! not a particularly good source but you might want to try it if your snails wont have any other calcium options.

protein

20% of a healthy diet for snails is made of foods with high protein levels. too much or too little can hurt the snail and cause diseases. here is a list of protein-high safe foods you can feed your snail(s), and how much you should be giving them. (the colours are just the amounts of time you should be giving the foods in a week or a month or whatever time it is) im also pretty sure you should be picking and sticking to one method only.
bloodworms - once a week. doesnt matter if frozen or dried. if frozen make sure the worms are left to thaw before serving. if dried the worms should be mixed with a bit of water and left for a few minutes till they are fully moist and mushy. around 20% protein, and low in fats.
beans - twice a week. all kinds are safe. make sure the beans are fully soaked & have no additives added to them. around 15% protein, and low in fats.
dried bugs - twice a week. usually crickets or mealworms.. you can find them at most pet shops or online. make sure they are pure and natrual, and have no additives added to them. around 15% protein, and low in fats.
peas - twice a week. frozen or fresh. if frozen make sure the peas are left to thaw before serving. canned peas are not recommended. around 15% protein, and low in fats.
seeds - twice a week. hemp seeds, lentils, pumpkin seeds, sunflower seeds and most bird seed. dry seeds should be crushed and grated as much as possible. the seeds should be then mixed with water till they form a thick paste. around 15% protein, and low in fats.
snail mix - more information below. its just a bit more complicated ahaha
spirulina - spirulina is a type of algae. it can be brought as either powder, or a tablet. the powder is more recommended. it is adviced to mix it with other foods when feeding and only feeding very small quantities. spirulina should be soaked in water and left till fully moist and mushy. it has around 65% protein and it is high in fats & nutrients.
snail eggs - if you have crushed snail eggs that were laid by your own snails, it is recommended to feed them as they are also high in protein and nutrients.

snail mix
snail mix can be either homemade or bought. its created by mixing and finely crushing many snail-safe (and healthy) ingredients, forming a powder mix. it can contain any of the following:
Blood Worms
Calcium Powder
Cat Biscuits (with no added salts)
Dog Biscuits (with no added salts)
Dried Bugs (meal worms, crickets)
Flowers/petals
Dried Fruit
Dried Herbs
Dried Leaves
​ Dried Oats
Dried Vegetables
Fish Flakes
Meal Worms
Oyster Grit
Pollen
Pond Sticks
Seeds (Sunflower, Pumpkin, Hemp, Chia, Niger)
Spirulina

it then should be mixed with water and left for a few minutes until it is fully moist and mushy. it can then be placed on plastic saucer and put in the snail’s enclosure.
there are a few online sellers of Snail mix. remember to always look at ingredients listed and reviews before buying. the snail mix found in SnailPets is highly recommended.
