Fish at a glance
Fish are peaceful, beautiful, and a great pet if you love to watch more than cuddle. They're calm and allergy-friendly, but a healthy tank takes more setup and know-how than people expect. Two fish are asked about so often that they have their own full guides here — the betta and the goldfish — and this page is the place to start if you are still deciding between a tank of little schooling fish, one showy betta, or a pair of goldfish.
Betta Fish at a glance
Bettas have more personality than almost any other fish — they learn who feeds them, follow a finger along the glass, and flare their fins to show off. The problem is that nearly everything about the way they are sold is wrong: the plastic cup, the unheated bowl, and the "they like small spaces" story. Give a betta a heated, filtered five-gallon tank and you have one of the easiest, cheapest, most rewarding first pets there is.
