Hello everyone,

I am thinking of putting some fish in my office. I want to get some Piranhas, its something i have always wanted. Anybody own these badboys or have any expereince with them?

I always had Oscars and they are great, but want something more aggressive and exotic.

Im also interested in the Balloon fish, i saw one at the doctors office today and thought it was neat. For those of you that dont know, its a fish with spines all over its body and when feels threated it sucks water in and inflates to a balloon.

How about Oscar vs. Piranha?
