Throw it in a 2x2 stone pin with 1 (2 for safe keeping) doorframes all around as walls and use a Argi to pick it up and put it in and use whatever tranq to knock it... If u have no Argi just launch tranqs at it and run away it is not fast so it won't catch up
You don’t actually need a crossbow with tranqs for this— just a normal bow. Try to shoot it in the head in rapid succession whilst walking backwards. (Their slow so this is easy) Once you have it out cold, you’ll need lots of berries and narcotic/bio toxin. Then you got an Anky!
If you are taming an anky use a scorpion to ride and a cross bow as the scorpion allows u to shoot from on top and it is fast plus if u run out of arrows u can go in with the scorpion to finish the knock out.
Suuuuuuuuuuuuper easy to tame, just make sure you have plenty of tranq arrows and you’ll be fine just walking backwards. Just in case, though, know that he makes more knockback then damage. Also, find him at herbivore island from a boat, don’t worry about liopleuredons, they’re so rare, you don’t have to worry about them.
