When taming tusos, use a creature with good health, torpor, and no oxygen stat as the grab target. Quite a few creatures fulfill this criteria, but my recommendations would be:

*Turtle (small turtle, not megachelon)

*Dunkle

*Mosa/Plesi

*Megalodon

As for your mount, ride a basilo so the tuso won’t grab your mount instead.
