I dont know if it helps on other servers but taming these is very difficult cuz they swim fast and loose taming effectiveness very fast! But if u take it up with a pteranodon or an other flying creature u can tame it while u are in the air! Just place fish meat in your hot bar and press it and it will tame just like if it was on ground 👍 I hope this can help people taming otters much easier than normal😄 Try it and vote if it helps! Good luck taming☺️
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.
If you are playing on mobile you don't bring it a dead fish instead you have to feed it raw fish meat. Similar to what is done with the diplo or other dinos of that type you just wait for their hungry to reset as indicated above their head and then refeed them.
