THE PROPAGATION OF THE GOLDFISH

the only danger being a possible lack of aeration in the absence of plants, 
which should be guarded against by the occasional partial change of water. 
Where there are facilities for water supply and drainage an excellent 
plan is to arrange an overflow pipe and a constant very small inflow of 
fresh water. A sheet of glass suspended vertically over the tank, 
to which a very small hose is attached, will occasion a constant dripping 
to both aerate the water and moderate its temperature. A very consider- 
able constant water supply has been found to be objectionable, as the low 
temperature of the water direct from the mains in winter is injurious to the 
finer goldfishes, which have been bred and kept in a warm climate and lack 
the hardiness of the common goldfish. Snow water is usually fatal to the 
finer breeds. 
Goldfishes are sometimes kept over in tubs in moderately warm cellars 
without any attention or food, and though they have survived, this is\ an 
inadvisable practice and an unnecessary cruelty. 
Wintering in large aquaria and tanks is best, and should be adopt- 
ed wherever the facilities are to be had. Any unoccupied light room will 
serve, and temperatures above freezing are not injurious, except possible to 
the transparently scaled fishes, if no sudden changes occur. Under these 
conditions aquatic plants can usually be kept in growing condition to 
supply the required oxygen. ‘The water should be occasionally partially 
changed.
