Common name: Goldfish
Origin: China
Maximum size: Goldfish can be from 6inches to 20inches
Minimum aquarium size: 20 to 30 gallons is required as goldfish grow very large.
Diet: Flakes, daphnia, shrimp, vegetables.
Tank area: All over
Ph: 7.0-7.6
Temperature: 60-75 degrees
Lifespan: Anywhere up to 20 years
Sexing: The male goldfish is usually more streamlined than the female, while the female is usually bigger then a male of the same age. When looking at the anal openings of the fish, the female's openings are larger, protrude slightly, and are round in shape. The anal fin is also thicker and the anal fin has a heavier spine. The male's openings are small and oval, the anal fin having no noticeable thickness to it. It is almost impossible to tell the sex of a goldfish under a year old. However, the easiest way to distinguish between the sexes is when the fish is sexually mature, and ready to mate. It is at this time when the male gets tubercles which look like grains of salt on his gill plates and the spine of his pectoral fin
Breeding: Goldfish will spawn on their own quite easily, but spawning can be triggered by lowering the tank to 64-68 degrees for 1-2 weeks, feed your fish high protein meals often, and do more water changes. There needs to be a few soft plants in the tank for the female to lay her eggs on. After 1-2 weeks gradually raise the temperature on the tank to 75-78 degrees over the course of about 3 days. While spawning, the male will follow the female constantly with his head up her backside. This can make your female a bit battered, and if she gets too beaten up, she should be separated from the male for a few days. Eventually, the female will release her eggs, and the male will come behind her and fertilize them. Remove the plant the eggs are on and put it in a separate tank with no more then 6 inches of water salted to 0.3% and a sponge filter and keep it at about 76-78 degrees for optimal growth. When the fry become free swimming, they must be fed live brine shrimp. When the fish are 2 weeks old, they will start to look like fish. At about 3 months, the fry will start changing colours and eating normally.
