One can begin goldfish growing in a small way at very small expense. Four tanks or reservoirs are required. Any boy who can make a hotbed frame can make these. They should be in a series: No. 1, spawning pond; No. 2, rearing pond; No. 3, storage pond; No. 4, winter pond. Whether one makes artificial tanks or utilizes a natural valley, separated by little dams, it is essential that the four ponds should be so fitted that they can be emptied at will. They should be sheltered from cold winds and from direct summer sun. The spawning pond should be built first, and furnished with water plants as much like nature as possible. Female fish ready to spawn can be bought from growers. These men are reliable and know how to advise you. It is to their advantage to increase the interest in goldfish. While building tank No. 2, keep watch for eggs in the spawning tank. Laying begins late in April or early in May outdoors. The egg is no bigger than a pinhead, yellow, or cream-coloured. Look for them on the plants. Snip the twigs off with great care and transfer the eggs, twigs and all, into large candy jars in clean water; one hundred eggs is enough for a gallon jar. Be careful that the water is of the same temperature in the jar as in the tank. Eggs should be kept not lower than sixty degrees Fahr., and not higher than ninety degrees Fahr. They hatch in two or three days or at most in less than a week. Do not disturb the water. Sudden changes of temperature will kill the young fish. When the fish are three days old, they are pretty lively and will soon begin to need other food than that supplied by the egg. To transfer them from the "incubator" to the rearing tank is a delicate operation. Mr. Mulertt advises putting the tiny fish into a small, shallow, "nursery" tank first to make the change more gradual. The jar can be emptied very gently, fish and all, into this tank.
