Place the container / bag they are in, into the tank to let them get used to the temperature.
Step 1:- Leave them like this for AT LEAST 10 minutes.
Step 2:- Let some of the tanks water into the container / bag.
Step 3:- Leave for AT LEAST another 10 minutes. This will let them get used to the different water chemistry gradually.
Step 4:- Repeat step 2 and step 3 until the container / bag is about three quarters full
Step 5:- Allow the snails to move out of the container / bag and into their new home.
Like most aquatic pets, your snail requires de-chlorinated water. You can use any readily available de-chlorinator product from most stores as long as it does not contain any medications or metal derivatives.
Your tank pH level must be around 8.0. You can purchase pH testing kits at your local fish store. To improve your pH level, you can utilize one of various remedies. Add cuttlebone (from the bird section) but be sure to remove the metal clip before adding it to the water. Partially bury the cuttlebone in the gravel so it doesn't float. Some people use crushed coral to replace the gravel. You could also try adding seashells to the tank. Just be sure none of the snails can lodge themselves inside any of them. To prevent this without fail, use “clam” type shells or shells much smaller than the snails themselves. I've also heard of people using reptile calcium supplements but have not used them myself.
PLEASE READ THIS.
Copper is highly toxic to snails and as they'll consume any left over fish food, it's important that your fish foods (and water) are copper free. Aquarium medications and tonics will kill them, as will any food that contains trace elements of copper.
PLEASE CHECK YOU FOOD
King British Plecostomus Tablets, King British and JMC Catfish Pellets are just THREE that I know of that contain copper. There are more, so check those ingredients on the labels.
It will be necessary to provide food for your snails, in addition to what they scavenge from your fish. Adequate foods include: Algae Wafers, Tropical Tablets, sinking shrimp pellets and any other types of sinking food for scavengers like catfish & loaches. They also enjoy rinsed canned green beans, peas, carrot, lettuce, cucumber and spinach (also a good calcium source).
The general rule of thumb for tank size is 2.5 gallons per snail. This, of course, depends on the adequacy of filtration & aeration. Your tank must also be totally covered. If your hood has holes, like many do, where the filter & heater hang – simply use aluminium foil shaped to securely fit the holes and poke some ventilation holes in it with a skewer. Similarly, other people have told me they use duct tape to cover the holes. Apple Snails can and do leave the water.
Good fish roommates for snails include, but are not limited to, Danios, Guppies, White Cloud Mountain Minnows, Neon Tetras, Cory Catfish, etc. All of these are non-aggressive fish that cohabitate easily with snails.
Some definite fish to avoid (in most cases) are: Oscars, most Goldfish, Cichlids, Angelfish, Puffers, Loaches, Barbs (most species) and some Bettas.
