soria powder may be sprinkled over the 
surface of the water at once, and the 
minute animals will be present by the 
time the fry are ready for them. This 
powder may be made by drying aquatic 
plants or lettuce leaves, and can also be 
purchased for a small sum. This micro-

The eggs of the goldfish are amber- 
colored, transparent and gelatinous, but 
infertile ones soon turn milky-white. 
These should be removed, for they are 
quickly attacked by a fungus, which may 
extend its activities to the fertile eggs. 
Hatching takes place from four to ten 
days after spawning, being dependent 
upon the temperature of the water, which 
must be kept as even as possible, and 
under no circumstances allowed to drop 
below 60 degrees.
