The Care of Fish.

Fish should be allowed a gallon of water each, that is, for every fish ot medium size, say three inches long. The bottom of the aquarium should be covered one-half inch deep with sand; there should be water-plant enough to furnish the fish with oxygen and absorb the carbonic acid, and also a few tafl-polee and snails to act as scavengers. These conditions are for a self-sustaining aquarium, where no change of water is necessary. If, on the contrary, the fish are kept in a globe, say of half-gallon to two-gal-lons capacity, with four or five fullgrown fish, at least half of the water must be changed daily. If the fish are but half an inch or two inches long, and each one has a half-gallon of water, water need be added only to replace the loss by evaporation. Whenever the fish come to the surface, it indicates that the water or part of it at least, should be freshened. They should be fed each day only as much as they eat up dean.— Indianapolis News.
