Thanks Rick, the offset was intentional. dead center aquascapes in frewshwater are a big no no. I understand in SW that a lot of scapes are function over form. The object is to make it easy to clean the glass, increase the area that can be used for corals, and to showcase everything equally. I personally can't bring myself to end up with another middle mound like the other nano tanks. In hindsight... I should have gone with the smallest rocks so I could better build a unique structure.
