Feng Shui: Goldfish in my bedroom?

I live at home, so can only really redecorate my own bedroom. I was looking on Yahoo! about Feng Shui and thought it'd be cool to bring some luck and love into my life by having a fish bowl in my room. Some people say 6 gold, 1 black fish, some say 7 gold and 1 black goldfish. Does anyone know for sure?

I was also reading some other answers/tips about Feng Shui and a person said not to put water features in your bedroom like an aquarium.

That puts a damp on my idea of putting a fish tank in my room.
Is it true that gold fish need 5-10 gallons of water each? That is an awful lot! Maybe 2 gold and 1 black goldfish is okay?

Love your opinions and expertise!
