Waterlily?

Tiger lotus is a very large plant. Individual leaves can be up to 6 inches across. If you trim them before they get that big and you trim the floaters then, yes, it can be made to work as a solitary plant in a smaller aquarium. I started one myself in a 10 gal but moved it to a 55 once it to too large rather than continuously trim it. It can be a lot of work.
