FishVille Battle Tanks coming soon
"With Battle Tanks you can enter your fish in combat to win great prizes! The more you compete, the more you'll build up your fish."
Finally, a feature to end our endless disputes and a way to train our fish! If you're as excited as us to plunge our well-trained fish into the Battle Tank, keep checking back here.
FishVille's fan page says this awesome new feature will be kicking off very soon.
