It doesn't really matter. You just want something that will allow you to place the food on the coral with some accuracy.
Just as an example, here's what I'm using to feed various corals in my tank. This tube is about 1.5" long, & about a 1/2" in diameter. I got it at my LFS. It's basically the same thing as the uplift tubes used in a freshwater tank, only smaller.
