This dino is very useful for caves. Heres how you tame it! Yiu need to build a 2 × 2 stone trap with doorways. Its kinda fast, so beware! Whatever you do, dont approach it in water while its swimming, because its special attack is a tail whip that will stun you for 10 seconds. It eats fish meat and required regular kibble (on pc and console) and pachyrhino kibble (on old phone ark). I really hope this helps. Good luck taming, fellow dino nerds
