Goldfish Water Requirements
The optimum temperature for fancy goldfish is 68° to 74° F, while comets and shubunkins should be kept between 60° and 70°F. pH is not critical, but ideally should be between 7.0 and 8.4. Rapid changes in temperature or water chemistry can be harmful, if not fatal to goldfish.Goldfish can require a moderate amount of care, but they are generally considered to be one of the easier species of fish to keep. They need a tank with a filter, regular water changes, and appropriate feeding. However, they are quite hardy and can tolerate a range of water conditions.A tank in a well lit room will get enough light for the goldfish to move around. Your goldfish will eat while it is light out. It is best to avoid sunshine as your source of light, it can heat up your aquarium quickly and the sunlight can encourage algae growth.

What keeps goldfish happy
Good water quality is critical for keeping a goldfish healthy. The pH should range between 7-8.4 and temperatures should be kept in a narrow range. Water should be tested frequently and an aquarium should be cycled before adding any animals.Because of the question do goldfish see in the dark or not can goldfish see in the dark. The short answer is no although they have good eyesight goldfish cannot really see in the dark.
Do goldfish need darkness to sleep
If you turn on and off the light at the same time every day, goldfish will typically follow the same sleep pattern. The light should not be on for more than 12 hours a day, or fish may not get enough rest. If it isn't dark enough for them to sleep, they may hide in plants to seek out darkness to try to sleep.
Goldfish can go without food for 8 to 14 days. During this time, they scavenge their aquarium and feed off algae. In ponds, depending on the size and available algae (sometimes goldfish also eat plants, check out this list here) and insects, goldfish can go without feeding indefinitely.
How do I know if my goldfish is unhappy
Bumping or rubbing against tank decor can also be a sign of illness. Another sign of illness is swimming in the wrong part of the aquarium. Surface feeders that start spending more time at the bottom of the tank may be in trouble. Healthy fish also tend to have a more vibrant color.Whilst they like company they don't like being crowded. They're not aggressive fish but they can get irritable with each other, and competitive over food if there are too many fish in the tank.No. Fish need a light and dark period each day for proper health. I like to give goldies 10 hours of light and 14 of dark so their brains think it's winter, and maintain a fairly steady, low metabolism, with less algae on the tank walls. Fish actually sleep, so turn off the light each night (but not the filter).
Goldfish are cold-water fish, so the pond should be located in an area with at least partial sun. This will help keep the water warm enough for the goldfish to thrive and allow your pond plants to grow.
How can I tell if my goldfish is happyHappy fish are healthy fish that actively explore their surroundings, enjoy mealtime, have plenty of space for swimming, don't have any obvious signs of illness, and get along with their tank buddies.
Should you leave a light on for goldfishNo. They go through a day/night cycle. They sleep, but it can be hard to sleep with a light on, so the light should be turned off at night. They don't sleep like we do, but they still do it.
Is it OK to feed goldfish once a day
The goldfish diet should contain a high carbohydrate level. Any freeze-dried food should be soaked first to avoid digestive upsets. Feed 2-3 times daily. It is important to avoid overfeeding goldfish as this can cause indigestion and/or contaminate the tank.
In general, you can likely leave your fish without food for up to three days safely, no matter the type of fish. However, if you plan to leave for an extended period of time, you'll need to prepare the tank.Rapid breathing: Rapid gill movement or gasping at the surface for air is a sure sign that your fish are stressed by poor water quality or low levels of dissolved oxygen. Hiding: A stressed fish may spend more time hiding under or behind tank decorations.Some goldfish do just perfectly fine living alone, but they really do like to be with other goldfish.
