'You mean like this...

something a little less scientific and more hobby oriented would be better
Pictures of the fish or corals, preferred tank parameters (flow, lighting, etc)
Feeding or dosing requirements, etc
Most times when I am looking up fish or corals that I am unfamiliar with I end up at the LiveAquaria website...so something along those lines but not sales based would be very cool.
