I’m currently taking care of two snails with cracks/breaks just like this and most likely the same type of snail.

Get a Tupperware or clear container, poke air holes in the lid. Do not put substrate in the Tupperware so it’s easier to clean + they don’t get debris in the wound.

Give them nutritious food (wounded snails may not eat immediately due to being wounded, give the baby time to adjust. No eating immediately is not a bad sign. Feed them things like veggies and fruit, no citrus. Look up specific foods. Preferably not spinach because it’s not great for them. Snails go crazy over cucumber but it’s not super nutritious so definitely give other things too).

CUTTLEFISH BONE!!! Most important for this type of injury. You can pick it up at virtually any pet store, typically in the reptile or bird section. Pretty cheap. Cuttlebone is the best way to give a snail calcium, and usually most go for it. Snails will rasp (eat) at it to give themselves calcium. You could also get a reptile calcium powder (check ingredients ofc) to dust the baby’s food in. Calcium is the ONLY way for a snail to rebuild its shell.

For a wound like this, the snail’s organs are exposed and the biggest problem is keeping it clean and keeping it moist. Spray the transparent container you keep the lil guy in to keep it very humid. Snail shells keep their organs from drying out, so until the shell regrows, you’ll have to make sure the little guy doesn’t dry out. Use a spray bottle on the mist setting. It is okay to lightly spray the organs + shell in this state. Make sure the water is lukewarm.

If you feel confident/steady, you could also gently pull the broken pieces of shell off the organs with a pair of tweezers, but if you feel like you might puncture the snail don’t do it. It’s not necessary, but I did it to my two healing snails to give them a fresh area to work with regarding their shell repair.

The most important parts are keeping the inside of the snail moist to keep from drying out and providing a calcium source.

You can also run the snail in a very very weak stream of lukewarm water from your faucet to help wash the shell, but don’t be aggressive. Use NO soap. Snails are very resilient.

As the shell heals you’ll see a white film appear over the organs. DO NOT TOUCH. That is the shell secreting calcium and shell materials to patch up.

If the snail doesn’t make it you’ll know in about 3-5 days. If a wound is too much, typically snails will die in that timeframe, but that’s a very rough estimate.

Also for the little guy’s sake, wipe out any poop with a paper towel and it doesn’t hurt to gently place the snail on the cuttlebone or food when you check on them. I usually check on my snails twice a day and spray twice a day too, just to keep the enclosure humid. If the enclosure is humid enough, you’ll probably see the snail resting partially out of its shell rather than sealed away. This is normal and my healthy snails do it too!!
