On mobile for me they always spawn wayyyy out in the sea cuz I was traveling with my dolphin and I found loads of them in the middle of the sea tip get a raft if your gonna try to tame them and bring honey because if need is on to you just throw the honey in the water it pacifier the leed and grab your place on the raft and go hoped this helped

Sorry for bad spelling bring honey to pacify the leedsicthys just throw it in the ocean idk why but I pacifies the leedsicthys
