First off, fish are living creatures, not decorations. Secondly, goldfish require 10 gallons per 1 inch fish (yes, TEN GALLONS) in a filtered water in an aquarium to survive. The secrete tons of ammonia through their gills and bodies and the ammonia and nitrate levels in a plain old goldfish tank (the old fashion round kind) can kill them in as little as one day. And in general, they are dirty fish meaning you will have to change their water almost daily etc etc and plain tap water will kill them.
Sorry, I'm not a goldfish nazi or anything but I have learned alot about fish care through trial and error and while goldfish are cute and inexpensive, I don't consider them disposable (which, lets be honest, most of them are going to be).
Stick to flowers. Or better, float some lit candles in large bowl alongside some orchids. This would be pretty.

Aren't I cute?? (except this tank is too small for me)
