FishVille Battle Arena fish swarm in-game store

FishVille is in the process of launching a special Battle Arena, where -- from what we can tell -- you will buy certain fish, train them and then send them into battle. While the details on this new feature is a little hazy, the actual fish that will be doing battle have arrived in the store.

Right now, there's five battle fish in all -- two cost coins and the rest require a small investment of a few Sand Dollars.
