Hi, I am planning a south American biotope aquarium with Apistogrammas tetras etc, I will not be using many plants but I am planing on having a large Echinodorus in one part of the tank with its leaves comming right out the tank. I would like to know if any one knows of any that would be sutialble for this, I was thinking of something like E. macrophyllus, E. cordifolius or E. grandifolius. How big a problem will the leaves drying out be? Are there any that are less likely to dry out? Cheers.
