I think the best for you is to visit as many shops or people with the sort of fish you like so you can see them in the flesh as I find the majority of the time pics dont do fish justice. Personally although I adore my Fronts they are very shy and really expensive for a fish you dont see alot of. I have just had to change my lighting on my front tank to blue else they would not come out with white lights on! could be just my crazy gang
