The tank also comes with a lighted hood, so that you can see your fish better. It also comes with a small filter, which will keep your tank clean, and minimize changes. Although do keep in mind that you will need to buy rocks or gravel, and plants. Also the filter will need to be changed one a month($2 for a new filter)

. no offense to all of you that work at petsmart and know a lot about fish
.
One time they recommended a 2 1/2 gal. tank for my cousin to get an oranda goldfish, that get to be about 10 inches!!!
So i might consider if you wanted a bigger tank to get it @ petsmart, and to get your fish from somewhere else!
