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 :)
