Would a 35 gallon be good enough for a barbouri seahorse?

If you don't care about breeding the seahorses, then you don't have to worry about the height of the 35g.
Height is more for the pair to be able to transfer eggs from female to male pouch during the mating dance.
DanU at seahorsesourse.com has reported egg transfers with little height, implying that sometimes they find a way anyway.
