So I would like to have a floating plant that grows nice roots downwards so that I have something pretty in the top part of my tank and to provide extra hiding spots for any fish I get . I love the Red root floater and frogbit. However, I obviously have plants in the tank so I don't want the light to get blocked too much. My question is how can I keep either of these plants contained to maybe half the surface or maybe in the two back corners? I read about fishing line but how do I do that? Also, if anyone has any other recommendations for getting the top part of my tank to not look so plain and more fish friendly I'm all ears! Oh I'll also say that I'm flirting with the idea of ditching the hood and getting a better light so I can enjoy any plants I have floating.
