I found lvl25. First time eat 1 element, secondary eat 3 elements and 3rd time eat 5 elements and at was 5.8% taming and 4th eat about 9 elements and completed this tame... Very fast will hungry... If you tamed and very hungry your dolphin then you need drop raw meat in inventory.. Dont eat element only when you tame!!! Little aggresive but beautiful animal
