Tame a kaprosuchos and swim to one of these bad boys and do it's alternate attack it will grab it in it's mouth. walk onto the shore where its safe and have another person feed it while in the gators mouth (if you unmount it drops it) it wont attack or die because it's technically not on the shore.
Surprisingly in mobile ark, if you attack achatinas with raptors, as I have learned from my own experience, you can get angler gel. I have never gone past the shallows in the ocean, yet I have multiple stacks of angler jell. Hope y’all can find this helpful. Don’t know if it works on other versions of ark though.
Get a basilosaurus and get the manta you want to tame, agro it to the balsilo and you will be able to tame the manta since its attacking the basilo instead of you. (The basilos food will drain quickly so get it some food)
Just pump health and when I mean pump health I mean PUMP THAT HEALTH! These guys die so quickly. I know it says on stats they have 320 health at level 1 but seriously they are so STUPID! in the wild, they sometimes jump in the middle of the most unuasual time and they instantly die even if the Manta is level 999 and even if its tamed it will only take MAXIMUM 9 seconds to die on land. AND ALSO IN BATTLES I DONT KNOW WHY BUT IT FEELS LIKE THEY HAVE HEALTH DEBUFF cause apparently they die so quick, especially to megalodons. Weird...
So just pump health.
Beginners Guide To MANTA: Cute Club
Hand fed and good pet! Need an itchy to tame.
1) Obtain sixteen angler gel (should eat less, but prepare!)
2) Ride an Itchy near the manta
3) Feed angler gel
4) Once tamed, equip a saddle. DO NOT RIDE NEAR any aggressive animal. It is NOT like the Itchy.
When taming place a stone foundations with doorframes on all sides except for one in the water with doorframes just under the water, aggro the manta in the spot and place a doorframe to lock it in. You can feed it while it aggro to a wall for safe taming.
These things are tricky to tame but I lure one to shore and put fence Foundation and then walls not a specific kind and then feed it angler gel which i got from killing anachita great tactic for lower level players
