Tank size, stocking, and info

[TomDug]

I'm new to marine fishkeeping and already have a 20 gallon freshwater aquarium, and a 10 gallon freshwater. I have been studying saltwater for years now, and I think that after going to the PPG Aquarium, I would like to try a reef tank. I'd either like to get a 30 gal, 40 gal, or 55 gal tank. I have made a list of livestock that I would like to keep :
Maroon Clownfish
Firefish
Coral Beauty Angelfish
Yellow Watchman Goby
Bangaii/Pajama Cardinal
Green Chromis
Coral Banded Shrimp
Pistol Shrimp
Peppermint Shrimp
Zoanthids
Zenia
Feather Duster Worm
Condylactis Anemone
Could you could tell me the best fish/invert combinations for my tank sizes?
Will the Anemone kill any corals or eat the clown?
I'm getting the list from my local Petco and I know they have a bad rep, but the aquatics specialist is very knowledgeable. I can't ask him many questions because he's off work on my free days.
I don't want to keep all of the above mentioned fish but, I would like a idea of what can go inside the different aquariums at once. Thanks ahead, -TomDug

I would go with a 40g or 75g tank. I say this because the narrow size of a 55g really makes it hard to aquascape a reef. A 75 isnt much more of a cost and provides a better footprint.

All of the fish you have listed do not require really large tanks, so they seem fine. I would stay away from the Condylactis Anemone. They move around a lot and can sting coral. If you want an anemone look more into a bubble tip. Also the Condylactis Anemone will not host your clown.
