Hi!! If you really want to keep these please get a 5g (or 10g) tank with a LID,a 5g is perfect since it is generally reccommended to have 1g per snail!! Get coconut coir (Eco Earth) for substrate and shouldbe about 3-5 inches deep. Do not get any ceramic food dishes or anything as they can fall from the top onto it and break their shells. For decor you can get such things as sphagnum moss, cork bark, leaf litter, branches and sticks, make sure if you do these that they are non toxic and no fertilizer or pesticides have been used on them. Get one or two PLASTIC plant pots for them to hide in. Mist the tank daily with a spray bottle to keep up humidity. I see you gave them spinach, i dont reccommend that as I have heard horror stories of people feeding it to their snails and them basically having an allergic reaction to it, but feed it at your own risk.
Some safe things to feed snails
- carrot
- apple
- banana
- romaine lettuce
- strawberry
- cantaloupe
- cucumber
- grapes
- watermelon
- kale (small amounts, as it contains a lot of calcium, which can build up in a snail’s system and potentially kill them in very severe cases)
- peach
- spirulina
- sweet or normal potato
- mango
- peas
- blueberries (smashed or cut in half)
- pear
- cabbage
- soaked algae flakes
