Are you allowed to ride it if you grab a fiendish animal?
You could attempt to but the creature doesn't learn any skills or training over time beyond what's in the bestiary profile.
Just going by a quick browse of the Ride skill rules...
It would at best be like riding a non-aggressive but otherwise wild animal. At the least it would not be combat trained, baring spells or such to give it that temporarily, so "Control Mount in Battle: As a move action, you can attempt to control a light horse, pony, heavy horse, or other mount not trained for combat riding while in battle. If you fail the Ride check, you can do nothing else in that round." would apply, and it would most likely fall under "ill suited as a mount" per the skill description so that's a blanket -5 to your ride checks as well.
So yes you can but good luck with that until you address those issues.

Okay thanks, using the Wartrained Mount spell should help then.
