I was always scared of these till I realised they are just small less-powerful but faster rexes. They aren’t that hard to tame just build a trap or tame in an small open area or hole because these are fast. Very easy to kill with a Rex or spino or even an argy. Have 5 and set them to be a killing machine by setting th relaxer to aggro and letting the others follow. They just have a slight problem with getting stuck on beach rocks and each other.
