Yea man, the nemo will only work with a 100 gallon + tank. Invest in a larger tank, or bring the larger fish bak. Sorry bout that, but the reality is, its unhealthy for the fish, and the movie was kinda a ..."cartoon". Notice how the sharks were trying not to hae a "no fish convention", and the hippo tang knew how to speak whale? Then the whale actually gave me a ride. WOW! just pulling yer leg, but yea, u need to make some chnages in order to be successful steve.
