IN SHORT 303 



Don't forget to allow freshly-drawn water to stand before use, especially 

 in winter. 



Don't depend upon running water, but balance your aquarium with proper 

 conditions. 



Safety requires a week's quarantine before placing new fishes in with 

 your stock. 



Take occasion, once in a while, to give your fishes a meal of chopped 

 earthworms. 



First look through a catch of daphnia for enemies before feeding them 

 to the fishes. 



Don't treat diseased fishes with salt water in an aquarium containing 

 plants or snails. 



Don't be stingy, but give away a few interesting fishes to those who might 

 become fanciers. 



Don't use aquatic plants at all unless the aquarium is near a window 

 with plenty of light. 



Don't suppose that a few plants can do much water-purifying. A liberal 

 number of them is needed. 



Don't, as a beginner, purchase aVgoldfish with very long fin development. 

 It is apt to be past its prime. 



Don't attempt to keep aquatic plants in a very subdued light. They 

 cannot prosper and only do harm. 



Even though goldfishes and certain tropicals get along together, it is better 

 taste to keep them in separate aquaria. 



If your home must be shut for several days, don't worry about the fish 

 starving. They will be all right if the temperature is correct. 



Don't resort at once to chemical treatment of a fish a little out of condi- 

 tion. A change of food or of aquarium may be all that is needed. 



Don't overlook the great possibilities of the native fish aquarium, both 

 freshwater and marine. The terrarium, too, is well worthy of at- 

 tention. 



Don't keep fishes in galvanized iron or zinc receptacles, nor have copper or 

 brass in contact with aquarium water. Unseasoned wood is bad; 

 unseasoned concrete, fatal. 



If goldfish are to be brought indoors for the winter, wait for cool, but 

 not cold, weather. A great change in temperature, even when gradu- 

 ated over several days, is injurious. If possible, fill the aquarium 

 with the same water they had outdoors.
