To tame it I recommend trapping it in a behemoth gate cage kinda like a taming pen. Then hit it once then it will agro on to you. Then lead it into the gateway and then close the doors behind it and then. Ik I should’ve said this but. Build pen in shallow water. Then to tame it agro tiny silver wish called microbe fish. There in deeper water. Then lure them in with the the turtle and they will lose agro and the turtle will eat it. BUT it takes an UNGODLY amount of time. Thanks me later 👍
