Most of the taming tips are trash and fail attempts at being funny. My guide after taming 4 130 to 150s turtles as follows.
1. Kite parrot fish swarm to turtle
2. Stay far away from turtle and swarm but do not put them out of render
3. Only approach to intercept sharks approaching the turtle and return to distance after killing hostiles.
4. Wait for bar to fill.
5. GGEZ turtle fortress :)
They have patched the render range range so ignore any tips that say to leave render as it will no longer. Guess I’m stuck with the turtles I have, I’ve spent three hours trying to take one of these things and had it walk out of the water which reset it taming! It was at 80% that time. Never got it above 20 after that. What he for the saber tooth salmon that spawn to kill the swarm if they bite the turtle it resets to zero and you start over. Extremely frustrating way to tame a creature. I would like to beat whoever came up with this idea.
