Are Ozelots substrate rooted or do they have to be attached to driftwood like Anubias do?
I also like the looks of Echinodorus Angustifolia "Vesuvius," but SA doesn't have the difficulty rating or how big they get...
Banana are aquatic, but I agree with kitten that they frequently do not do well. They also generally only last about a year. I tried them years ago, would not bother again personally.
Pennywort is great floating; Frogbit is difficult to find it seems, but more to the point I find it very difficult to cultivate. It is about the only plant I currently have that does well for a time then dies off almost completely. I have it in 3 different tanks to experiment, but the same in all 3. Pennywort will be fine though.
All true swords (species in Echinodorus) are substrate rooted. While they can sometimes be grown on a piece of real wood, it is safer to plant them in the substrate.
Echinodorus angustifolius [this is the correct spelling, though it is frequently seen with the "a" ending] is a species in the pygmy chain sword group. Submersed growth will be leaves up to 30cm (12 inches) but sometimes up to 50cm (20 inches) depending upon light, parameters, nutrients. The pygmy chain swords can grow quite differently from one aquarium to another. Technically speaking, the pygmy chain swords are now in the genus Helanthium; I posted an article on this change in the Freshwater Articles section, here's a link to the article if you're interested: http://www.tropicalfishkeeping.com/f...37/newmessage/
As noted therein, many nurseries and aquarium plant suppliers are already using the new name, but the long-standing names (Echinodorus tenellus, E. angustifolius, etc.) will likely be around for quite a while as the pygmy chain sword is a very popular plant.
