Front caption: How to care for an Aquarium. Use pure water, which should not be changed; it is better to introduce water plants, which will supply oxygen for aeration. Put fine washed gravel or coarse sand in the bottom to hold roots of the plants. Keep the aquarium in the light but not in sunshine; it should be in a room where the temperature is uniform, 50 to 60 degrees. A ten-gallon aquarium is easier to manage than one of smaller size. Do not crowd the specimens; a few small fishes will thrive better than several large ones. A rectangular or round aquarium is better than a globe. Feed moderately as waste food will foul the water. It is best to buy prepared foods. Put in a few fresh-water snails to eat green moss off the glass, and a couple of tadpoles to help clean up waste food. Take out refuse with a rubber syphon. Destroy fishes which become diseased. Get an aquarium book and study important details; the New York Aquarium can supply "The Care of Home Aquaria" for 25 cents a copy.
