try a crypt spiralis??? Hopefully someone knows what plant I am trying to talk about. I really like the tank but I would agree with Fort about the preference of having a more open middle. Even if it was just one rock...
What fish are you planning on having with your Rams? I wish someone would have told me my serpai were fin nippers, they nip at my male rams long fins keeping them shorter, and look a little duller. IMO I would avoid nippy fish and your male will look better.
