I have a ton in my 5.5 gallon. It all grew from one small specimen I got about 12 years ago. Even put three in my 20. Have maybe 15 or more in the 5. Lovely plant.
I'm getting 5 plants to start and am planning on putting them right in the front but since you have them do you think they will get lost in the grand scheme of things even in such a predominant spot?
