Thanks Big Mike. I am liking this one better now that I got the underwater plants in there. I chose that Cryptocoryne pontederiifolia because it has the long leaf petioles, so the nice rocks are not covered with foliage.
Thanks Ika4040. That plant is a good one, Cyrtosperma johnstonii. It belongs to an unusual group of wet habitat tropical aroids. Here are some other views.
Their meetings and shows (usually in Florida) are great places to see and acquire rare and unusual aroids. The newsletter and annual journal publication have a lot cool scientific information.
Two of the most popular groups of aquarium plants, Cryptocoryne and Anubias, are aroids.
