Some other colorful fish you might want to consider:
Yellow Clown goby (bright yellow)
Clownfish (only get one pair, of same type)
Blackcap wrasse (purple with black head)
Royal gramma (yellow and bright pink)
Orchid dottyback
Firefish
Watchman gobies (I like the yellow)
There are lots of beautiful fishies- your best bet is finding out which fish you MUST have, and see what other fish are compatible. I have 2 clowns, a royal gramma and a blackcap in my 55 gallon. I'm limited in what I can add now though- My clowns are bullies, and tend to pick on peaceful fish.
Go to J&L in burnaby. Also, their website has tons of pictures, of just about every fish. That should give you an idea.
ETA- I have 2 skunk shrimps, they were our first purchase. I was so delighted witht hem, I almost considered having just a shrimp tank. Fun to watch, and brighten up the tank.
