V. Feeding Goldfish. 



In the March number Mr. Wm. T. 

 Innes, Jr. discussed at length the feeding 

 of goldfish and I doubt that I have much 

 to add to his able article, but this series 

 would be incomplete were I to omit this 

 most important phase of the study. 



I take exception to the statement that 

 one may "feed anything and everything". 

 I know very well that it is not meant to 

 convey the idea in a literal sense. The 

 amateur is apt to go astray in reading 

 such articles. It is true that a goldfish 

 will eat most anything the human being 



will eat that is nutritious. The expert 

 knows what to feed, when to feed, and 

 how much to feed, all of which the 

 amateur has yet to learn. I propose to 

 give much the same information here, 

 but in a different way. Bear in mind 

 that while goldfish will eat many kinds 

 of food without harm, there is a vast 

 difference in the kinds that will do them 

 the most good. 



The food par excellence is live Daph- 

 nia, Cyclops, Cypris and other minute 

 forms of life commonly called "water 

 fleas". In the summer these may be 

 found in most slow running streams and 

 stagnant pools where water is pure. Fry 

 given water fleas in as much quantity 

 as they will eat, thrive, get color and 

 grow up healthy in an astonishing 

 degree compared to growth when fed 

 other foods. The mosquito larva, or 

 "wriggler" is the finest kind of fish food, 

 but too large for very small fish. To 

 obtain wrigglers put a tub or barrel of 

 water outdoors containing straw, sheep 

 manure, grass or something of that 

 nature. In a few days the water will 

 be alive with the larva which may be 

 fed in unlimited quantities to fish large 

 enough to devour them. 



Next in order to water fleas and 

 mosquito larva, I consider dried shrimp 

 and Daphnio in equal parts to be the 

 best. During the winter I feed nothing 

 else. Many foods are prepared by 

 American fish breeders, the ingredients 

 of which are pretty much the same. A 

 number are advertised in The Aquarium, 

 all of which may be used with 

 confidence. 



Foods which may usually be obtained 

 from the kitchen are oatmeal, both 

 cooked and dry, ground dog biscuit, 

 yoke of thirty-minute boiled egg, finely 

 chopped raw liver, or liver dried and
