Whatever you get,
be sure to cycle your tank first. I assume that it's not yet cycled because you plan on bio-spira? Angels are sensitive to water conditions so, IMO, it would not be wise to make it your first fish. In case a spike occurs, I would get hardier fish in the first few months of establishing the tank. I think a few tetras were mentioned along with corycats.
I think nothing looks better than a well planted tank with fish occupying top, middle, and bottom sections. I wish you luck and when you're ready snap some pics too.
