That's a nice tank! What direction are you trying to go in? That is, what are you trying to accomplish and what are your goals? It looks to me that you haven't made a clear-cut decision in that regard and to me, at least, the aquascape sort of reflects that. I know that it may seem a little counterproductive, but possibly narrowing down the corals you have would make the display look better to me, at least. I like a display of a few larger specimens as opposed to the bonsai look, though many do seem to prefer that. Anyway, answer some of the questions and I may be able to make more suggestions. Just remember, though, this is more in line with my aesthetic, not necessarily yours (though you may very well agree with it). What counts is whether or not you like it, not me. I don't have to live with it.
