For full Otter taming details, get the taming calculator app.
To tame an otter, kill some fish, approach the otter, and then use the action button to feed the fish to it. Level of fish does not impact taming. The Sabertooth Salmon is by far the most effective fish, followed by the Piranha and the Coelacanth. Please ignore timing and effectiveness as calculations are not yet complete.
I once had an otter that I named harry otter , he was a great otter he got me all the silica and black pearls I needed, he once saved me from a megalodon , he kept me warm to, he was a great companion I took him almost everywhere,but one day I was farming pearls with him I threw him at a fish to get pearls from it but instead he disappeared I looked and looked for him only to not find him but uneven got a message that he was dead, he's still out there somewhere, I still look for him to this day. #prayforharryotter
These little guys are so much easier to tame in mobile, but harder to find. You still need to kill a megipirahna, but you don’t need to grab its corpse to feed the otter. After harvesting its meat you can easily walk up to it and feed it until it’s tamed. It doesn’t run away in mobile, and I’m sure you can use any fish meat. Like so Dododex sees!
I recently had tamed a low level otter in Ark Mobile. When ot was tamed it had the weight of 38kg. When I took the otter to the cave for some reason it didn't allow me to place artificts to the otter's inventory
