I've never shown my aquariums on here, so this is a first.
I've finally rescaped my tank into something a little more decent. This is probably my first true aquascape.
I hope you like it.

The inhabitants:



And the flora:

Fauna: 7 Hemigrammus erythrozonus, 5 Hyphessobrycon herbertaxelrodi, 2 Otocinclus vittatus, and hundreds of Malaysian Trumpet snails
Flora: Ludwigia repens, Microsorum pteropus (2 varieties?), Vallisneria sp.?, Nymphaea sp. 'rubra', Taxiphyllum barbieri

The ludwigia on the left looks awkward to me, would it be okay to trim it down and let it all grow in a little tight bush? How do I go about in doing it, do I do slope it off a bit...taller in the back, shorter in the front...or just a bushy lawn all along the front on the left? I want it to get enough light without obscuring the view of the vals. Also I want to get a bolivian ram as a centerpiece I've had them before in this tank with no problem, will this do?

Any suggestions, feel free to do so.
