You can tell if your goldfish has a bacterial infection because the fin will look very ragged, while a fungal infection will cause the fin to rot away more evenly and there will be a white edge along the end of the fin.
By cleaning your aquarium water regularly, which for most aquariums is done by changing 15 percent of the water weekly, you can greatly reduce the chance of your goldfish from becoming stressed or sick.
If you want a clean, classic and conservative look to your lawn and garden, don't go with a gardener who tries to talk you into digging up a chunk of your yard for a goldfish pond!

GOLDFISH (Cyprinus or Carassius auratus), a small fish belonging to the Cyprinid family, a native of China but natur Telescope-fish.
The domestication of the goldfish by the Chinese dates back from the highest antiquity, and they were introduced into Japan at the beginning of the 16th century; but the date of their importation into Europe is still uncertain.
For descriptions of other Cyprinids than the carp, see Goldfish, Barbel, Gudgeon, Rudd, Roach, Chub, Dace, Minnow, Tench, Bream, Bleak, Bitterling, Mahseer.
The Prussian carp (Carassius vulgaris) is established in New Zealand, and the nearly-allied goldfish, a domestic form (C. auratus) of Chinese origin, has been widely distributed as a pet, and is feral in some places.
One of these, remarkable for its very short, thick head and deep body, is the socalled Prussian carp, C. gibelio, often imported into English ponds, whilst the best known is the goldfish, C. auratus, first produced in China.
The various breeds of goldfish are familiar examples, but the carp is almost the only food-fish capable of similar domestication.
