It is, however, very difficult to keep gold fish long in a room, particularly in a glass globe. When it is wished to do so, only two or three should be in one globe, and the water should be changed every day in winter, and twice a day in summer; the fish having no food but the animalcula which they find in the water, which should always be from a pond or river, as spring water is not only too cold, but often contains some mineral substance which is likely to prove injurious. When several fish are kept in a small space, the water should either be kept continually changing by a fountain, or in some other mode; or the fish should be fed with some farinaceous substance, but never with baker's bread, as it is decidedly injurious to them. I am told that the dealers in gold fish, who always keep a great number together in darkness, in a large tub or tank, feed them twice a day with boiled grits; other persons recommend crushed barley or oats: in France they use a kind of paste made of maize or Indian corn; and in America, I am told, they prefer brewer's grains, or a paste made of bran and flour. Whenever farinaceous food of any kind is used, it should be given in small quantities, and be quite fresh; the vessel in which the fish are kept being always cleaned thoroughly every day, to prevent the possibility of any of the food in a sour state remaining in it. Though gold and silver fish certainly look best in a glass globe, I doubt whether they live so long in one as they will do in an opaque vessel. When I kept my fish in a large oblong china vase, I lost only one in five years; but in a glass globe I lost seven in about six months. I tried various modes of treatment, such as putting gravel in the water, and giving the fish duck-weed and pond-weed to shelter them from the sun; but I had still the mortification to see my fish die, and generally without any apparent cause. The first symptom was the fish appearing languid and unwilling to move; but in a few hours, it began to swim on one side, and when turned on the other side it instantly resumed its former position; shortly after, the tail drooped down, so as to throw the body into an angular position, and in the course of a few hours the poor fish was dead. It is true that the year in which these experiments were tried appears to have been decidedly unfavourable for gold fish, as a great many died, even in ponds, where they are generally much more healthy than when kept in rooms. In one instance, especially, nearly twenty died in the marble basin of a fountain, where fish had been kept for years with an average of not more than two or three deaths in a year. In many cases, the cause of death in gold fish is evidently a plant nearly allied to the green scum formed on stagnant water. This plant, which is called Achyla prolífera, consists principally of threads so exceedingly fine as to be imperceptible to the naked eye, but which take root in the body
