No you don't need special hosing. 1/2" is okay to get from Home Depot/Lowes but when I got 5/8" from there it was so freaking tough it made it much harder to setup so I ended up getting Fluval G series tubing which was a lot more flexible. ADA makes 1/2" tubing that is flexible but you probably don't need that extra expense.
The tubing is pretty tough to get over the lily pipes so that creates a tight seal so you don't need anything extra. You could loosen the tubing up by running it through hot water for a minute and then it'll go over easily on the lily pipe. Placing the tubing a few inches on the lily pipe should be good. I've never had leaks.
