CARE OF FISHES 
O successfully raise and keep either 
goldfish or tropicals, it is essential 
that the outdoor pool be properly 
stocked with water lilies and aquatic 
plants; the indoor aquarium planted 
with oxygenating plants to produce 
the necessary oxygen needed for the 
fish. 
OVERCROWDING of fishes should 
be avoided. In outdoor pools, fish are 
hardly ever crowded. In the indoor 
aquarium, it is required to have one 
gallon of water for every 2 to 2% 
inches of goldfish body, or one gallon 
of water for 2 to 3 pairs of tropical 
fishes. 
Whenever fish continuously swim 
near the surface of the water, it in- 
dicates that the oxygen is exhausted 
and immediate relief should be given 
by changing part of the water, aerate 
it with an air pump or transfer some of the fish to another aquarium. 
Tropical fish thrive best at a temperature of 72° to 80° F., whereas 
goldfish require a lower temperature. 
DO NOT PUT TROPICAL AND GOLDFISH TOGETHER, 
FEEDING OF FISHES 
After years of experimenting, studying and raising various kinds of 
fish, both tropical and goldfish, we developed foods for all types of 
aquarium or pool fishes. 
Tricker foods are known throughout the country as quality foods, 
containing all the nutrients necessary for successfully raising fishes. 
For GOLDFISH, either in the pool or aquarium, we recommend our 
IN-NUR-CO to be alternated with SUN-CURED SHRIMP. Feed the 
goldfish every other day, as much as they will eat in ten minutes, 
Syphon off unconsumed food from the aquarium with a dip tube. 
For TROPICAL FISH, we recommend VITALINE, a new food we 
just introduced; DRIED DAPHNIA, which consists of carcasses of the 
tiny crustaceans of fresh water fleas, and SUN-CURED SHRIMP, finely 
prepared. Feed the fish three times daily in small amounts, not more 
than they can consume in 10°minutes, Syphon off any excess food. 
FOODS 
THESE foods are prepared and tested in our laboratories by our 
chemist and have proven excellent for both young and mature fishes. 
They are the only foods for all varieties of fishes, properly balanced, 
containing proteins, carbohydrates, mineral salts and other useful nu- 
trients necessary and essential for the growth and sustenance of fishes 
in aquariums and pools. Tricker’s fish foods are prepared especially 
for feeding in aquariums without fouling or 
polluting the water. 
VITALINE. The perfect fish food, correctly 
balanced. It contains all the nutrients 
and vitamins necessary to the growth and 
sustenance of either tropical or goldfishes. 
Tricker’s Vitaline will bring out the color 
in fishes and promote healthy, robust bodies.
