I have been interested in doing a south american biotope for some time now for my leaf fish. I know they really like to lay their eggs on echinodorus bleheri sword plant and they also really like to hide in a field of vallisneria. This is sure a big body of water to attempt to display in any tank. Of course you will need fallen driftwood and rockwork with most echinodorus sp. such as amazonicus, osiris, bleheri, horizontalis, Limnobium laevigatum and hydrocotyle leucocephala to start things off. Its late now, but I'll do further reading and post a few more plants for you. Gotta love those leaf fish!!!
