I've seen some great photos of people who pot their aquatic plants within the aquarium and I think it looks great! I'm thinking about doing that myself using a coffee mug and maybe a couple of shot glasses.
Are shot glasses going to be big enough? Will the plant send out runners or will the roots grow out?
