What fish should I add next

[clownbob]

This is looking like it will work for me. Another smaller clown and 2 yellow clown gobies and a cleaner shrimp.

I live in Cloverdale (Surrey). Are there places to buy new fish that are better than other places or ??

From my research it sounds like I should add fish one at a time. Would you recommend going with another clown first or with the gobies (I assume that I can add the two gobies together).
