Hejsan, Jag frågade under "foder" om någon kunde rekommendera ett kvalitets foder för GF typ Oranda/teleskop etc. Inget vidare gensvar (så är det ibland!) men jag sökte vidare på nätet och hittade nedsående artikel som talar om 28c vattentemperatur för de mer "odlade" GF och en artikel om foder och vilken typ dessa GF behöver beroende på ålder. Kanske någon finner intresse i dem.

HEATERS
The main reason that a heater is so important is that they keep the temperature steady. Fast changes in temperature from air conditioners, heating from a light source and then drop when the light goes out, etc. can highly stress the fish, causing disease like ich and problems like dropsy.
Although goldfish are "coldwater fish" this only means they will not die in colder water. It does not mean it is ideal for goldfish. Single tailed GF with short fins, like comets may do well in temperatures as low as 65-70oF. But fancy goldfish are raised and do better at higher temperatures 75-80oF.
A breeder of goldfish in China says
"1). We observed bacteria through microscope for some years we found:
bacteria can be found from 4 degree C to about 20 degree C. Among the range of the temperature, different temperature range have different kinds of bacteria. These bacteria can lead the deadth of goldfish.
If the temperature is over 34 degree C we can find other different kinds of bacteria. These bacteria also effect the safe of goldfish.
So 28 degree C. is the most safe temperature for goldfish. From our obvervation we can also understand why tropical fish have not so many diseases compared with goldfish. The temperature range tropical fish live have not so many bacteria.
2). We also supplied some goldfish for other people made some concerned experiments for a whole year. The experiments showed the temperature of 28 degree C is the most safe temperature for goldfish, and goldfish grows the most fast. But the goldfish can't spawning at this temperature. Spawning may effect the life of goldfish. Reducing the times of spawning can make goldfish living a long time.

FOOD
The ingredience list of some good quality foods is found here.
Live and alternative foods here.
The problem with typical GF food like flakes is they usually have been sitting on the shelf at room temperature for a long time. Vitamins, especially vitamin C which is essential for good health, degrades over time. Even when food is frozen vitamin C degrades in about 6 months.
Second is that high quality food contains more of the kind of food that is digestible by goldfish. There is a more complete discussion of this here.
High quality food contains more "real" food, so less of the food needs to be fed at one time. With high protein, high quality food, less fed means less waste and filler that fouls the filter, the gravel and the water.
GF cannot digest complex carbohydrates, so all the corn, wheat, etc that is not natural food goes in one end and out the other without much being digested. But all those carbohydrates are attacked by bacteria so fouls the water.
Up until sexual maturity, GF put all their food into getting bigger, after maturity (2-3 years) they put their protein and energy into making eggs and sperm first, anything extra goes to growth. This means when there is a limit on proteins/nutrients, they make as many eggs as the got resources for and quit growing. If you are happy with the size of your goldfish, a maintenance level of protein is suitable.
How much nutrition a GF gets out of food depends on how digestible and loaded with nutrients the food is, and how often they are fed. All digestion and breakdown of food into component building blocks occurs in the intestines and no where else. GF dont have a stomach like other animals, so there is no initial churning and breakdown with acids, no "holding" facility. From the moment the food goes thru the mouth, there is a "clock" on how much time there is to break down and extract nutrients before it exits at the other end.
If the food is indigestible, loaded with fillers, or poor in the kind of nutrients the fish can use, it comes out without much being extracted in food value. A lot of food at one time results in big poops out the other end that are filled with nutrients for bacteria that foul the filter. Normally GF browse all day, eating small amounts of food. So feeding small meals several times a day with high quality, high protein foods leads to the greatest growth. Generally, a mouthful means the fish scoops up food, stops and chews it. Two mouthfuls three times a day or 3 mouthfuls twice a day.
Shrimp and other water things are natural food, including the algae they munch on (altho I think they are after the goodies that are munching on the algae, like daphnia. GF are not vegetarian. High protein quality food for GF needs to be kept frozen to preserve the fats and vitamins. Vitamin C degrades even so after 6 months. Vitamin C is essential for bone growth in GF.
Fancy GF with fat bodies often have swim bladder/digestion problems with floating food. Just soaking floating food isnt enough, we have found it necessary to squeeze out the air so the food sinks. Is easier to prevent floaty problems by feeding sinking food.
A breeder of goldfish in China says
"In China, there are many kinds of nature food for goldfish. People also process some man-made foddor for goldfish. Among all kinds of nature foods, waterflea (daphnia) is considered the best food for goldfish. Blood worm is one of the best food for goldfish. Live food is the most welcome. But waterflea can live a short time (about one day) when put into tank and the life the bloodworm is much longer compared with waterflea. As we know some Chinese people export frozen and dried waterflea, live and frozen bloodworm to international market. Sun Hongliang"
