They are generally annuals and do not live indefinitely, and the most satisfactory ones are those handled by the dealers, since these are cultivated especially for the purpose. These for the most part have been introduced from the tropics, where they flourish perennially.
Stocking the Aquarium
The beginner should start as simply as possible with only the commoner and hardier fishes, and wait until he has proved successful with these before attempting to handle rare or expensive stock. Carps and the ordinary goldfishes known as "commons" are undoubtedly the best for the beginner who is within easy reach of a dealer. The highly bred, fancy varieties of goldfishes are less hardy.
