Advertisement I saw a series of youtube videos that started with setting up a filterless betta tank by using a sweet potato. There's probably a word for it, but I can't think of a better description than waterlogged roots. Anyways, I want to try out an aquarium like this, but I'd like to try plants other than a sweet potato. I know pothos can survive with their roots always being in water, but I'm not sure about any others. I'll probably experiment a bit. Do you guys think any plants stand out as potential candidates? Has anyone had experience with any plants living with their roots always in water?
