If you just got them and they are on wander, keep them away from each other or a bunch of babies will be born.
Achatina
The Achatina is a massive snail, mostly used for its production of Cementing Paste, or as a pet. This creature produces its paste passively — and quite frequently — so many survivors keep them around their bases. However, its usefulness pretty much ends there, as it cannot attack and moves quite slow. The Achatina must be tamed violently.

Player-written tips for taming, using, and fighting the Achatina in ARK: Survival Ascended & Evolved.
Don't tame, take 20+ of these to your raft and then to the base. They will not despawn anywhere.
Infinite cementing paste hack:
Step1: make 5 cakes
Step2: blast some random sail in the head and feed it
Step3: Name it “Gary”
Step 4: set to wander
Step 5: lock it up in a cage for the rest of its worthless life and throw the key in a industrial grinder
I had no idea how to tame this but I thought it was so cool. So I took it home and set it in a holding pen. I am a newer player and don't know how to make this cake so I can not say about "after it tames" but I do know that on mobile as of 12-30-2020 it never…
I had no idea how to tame this but I thought it was so cool. So I took it home and set it in a holding pen. I am a newer player and don't know how to make this cake so I can not say about "after it tames" but I do know that on mobile as of 12-30-2020 it never gave me cementing paste. BUT it does poop Achinta paste not tamed just wandering around in my base. Follow one untamed.
I Never knew this but I was killing then with my Spino and I got some Angler Gel. They don’t give nearly as much as an angler, but if you ever need a little bit, just kill these guys!
Random fun fact: this snail is actually on every map besides genesis part 1
They can make achatina paste which can be used as cementing paste which means you don’t need to grind for 5 years for just 30 cementing paste
Cakes are a pain to make, but the amount of cp and organic polymer you get over time is worth it!
Drop a bunch of tmwild or tamed snails in a pen and have a gacha next to the to pick up the paste
You don’t even need to tame these guys to get paste, just pick a few up with a flyer and put them in a pen and overtime they will drop some paste but you have to remember to collect it or else it’ll decompose
I love this gus and he is the best
WARNING! SNAILS GESTATE!
Don't mate them if u aren't going to be on in 8 hours.
Had to knock it out on switch to tame it. Super high torpor rate. Still eats veggie cakes
Flying them back to base with a PT doesn’t work.
Caves and Swamp have the highest chance to find. Bola and protect them with a cooking pot on the side in case you run ou of cake. After, put them in a pen or dino leash on wander to make paste and organic polymer.
Do You Want Cementing Paste, Tame The Achatina.
The cake diet is worth it for cementing paste
Hey you know you can like not take care of one and kinda trap it wild and it still makes a lot of achanta paste.
Which is better stat for these snails ? Health or food or both?
Put loads of stone in its inventory to let it wander without moving. If there is a bit space left for the the paste this works fine and you don’t need a cage.
