The swim bladder can fill by gulping air at the surface, this enables the fish to float or empty by loosing air from the swim bladder through a pneumatic duct (a pneumatic duct is an internal gas filled organ) connected to the oesophagus, this enables the fish to sink.
got this answer from another person. i really hope that it is right
Stop doing a handstand. If your goldfish is floating, it will float to the top, not the bottom, therefore, you must be upside down!
Can starfish survive in a fish tank with fresh water fish?
No. They are too weak to get along and they do not have fins so they can only stay at the seabed.
What kind of water do you put in the tank for tropical fish?
The most common tropical fish available for a home aquarium thrive in fresh water. For fresh water aquariums, people usually use tap water, but treat it first with commercially availble water treatments to remove harmful properties, such as chlorination (chlorine present in tap water will kill good bacteria that the fish will need to survive), and to obtain a pH balance that will be agreable with the fish. You can get a simple bottled chemical treatments at most any pet store.

AnswerSome are concerned about using filtered water (RODI) as it takes out the chemicals the fish needs. This is not an issue in saltwater aquariums as the salt mix will add the needed chemicals. This may cause problems in freshwater tanks, however preparations are available to add the missing chemicals in filtered water.RODI water is a must in Reef tanks - it saves problems down the track.

Can you use an airstone in a ten gallon tank?
This is a debated topic. There are both pros and cons. Though oxygen is very important, too much can be deadly for a fish. The finer the bubbles the more likely your fish may get air bloat. Also adding an air stone increases the CO2 gas exchange process increasing the pH in the water. Marine fish like basic water. Also in a reef tank too much oxygen can kill coral. Normally filter systems creates enough oxygenation for a tank to where an air stone is not needed. If you want air bubble for a decorative effect try to get something tha doesn't create a fine bubbles.

Why does my fish have black spots all of the sudden?
Black spots on a fishes body is a symptom of black spot disease( a disease caused by a digenetic fluke. It will usually go away on its own, as the complex life cycle of the fluke can not be completed in an aquarium.
Why do your cold water fish keep dying?
This question is rather difficult to answer, being that there is really nothing to go off of other than repeatedly dying fish. One of the fish probably introduced a viral, or bacterial, pathogen into the tank which has spread to the other tankmates and consiquentely caused them to die. Raise the salt concentration in the tank to 0.3% and treat the tank for parasites using an antiparasitic. It is also recommended to, if a bacterial pathogen is suspect, feed the fish an antibiotic food. If this does not help and all the fish die anyways you'll want to sterilize the tank before adding any new fish. You can do this using bleach as long as you let the tank sit for a couple days afterward.
i like the above answer however, i have an extensive knowledge of tropical fish-keeping and know about the benefits of using bleach as a cleaning agent & have thought about it but would never use it, to much risk involved.
cold water fish are for beginner's, i would recommend getting a water test by taking a clean bottle half full of your tank water to your local reputable fish shop.
Your goldfish is always at the top of the tank gulping at the surface is this normal?
If the water the fish is in is not changed regularly a goldfish will do this because the oxygen in the water is too low for the fish to absorb it through its gills so it gulps air from the surface of the water. Make sure you change the water in a fish bowl or get an air bubble pump for an aquarium and this will stop this behavior in your goldfish.
Goldfish always go to the top for oxygen. They are known to do this. This is why it is recommended you do not have a really tall tank. I have gold fish and never have a tank over 16 inches tall. In my 40 gallon that is 36" Long x 16" High x 18 " Deep. I have two gold fish that are about 3 inched long in size. But one is a black moor. Both go to top for oxygen even though I have two filters, a 45 and 40, plus two sponge bubbler filters, and two long bubblers in back of aquarium. They are quite healthy and never sick. In fact I saved them from Walmart some time ago. I do know it is better to have a tank that is not tall and goldfish will always go to the top for oxygen. They require more oxygen than many fish. I have another 4 foot long tank that is only 12.5 inches tall with black moors. They too, (as a species of gold fish) go to the top for oxygen. I keep water in top perimeters. and water change as needed. But if your fish show floating signs, give the fish peas. I give my fish peas once a week to keep them from having a swim bladder issue, but if they do, peas cure over night.
Try to have moving water as this creates oxygen. Try to have a tank that is not too tall. I have been told it is best to feed goldfish grandular food or pettet food. Not Flakes! My research has told me flakes can cause swim bladder issue in goldfish..

Why do goldfish lay on their backs?
Your fish is struggling, and probably near the end of its life, if you have not already discovered that. There is an outside chance that something from the pet supply store could help your fish, but I would not put a lot of hope in that possibility.

First of all, you could probably just take it back to the pet store. If you really need to kill it, the most humane way is to add some clove oil to the water. It will kill the fish quickly and painlessly.
Can you put female bettas with other fish?
Yes, females areusually not aggressive, but if they are than you should take them out, but besides that they should have no problem being with other fish, but the males are not as aggressive as everyone thinks. The male Bettas will ONLY attack other Bettas or fish with long, flowing fins BECAUSE they mistake them for another male Betta.
Why do the fish have a swim bladder?
The swim bladder is in animals that need something to help control their buoyancy. Sharks do not have swim bladders because they do not need this.
Yes, goldfish eat their young. This is why they lay so many eggs- most of the fry won't reach adulthood because other goldfish/fish will eat them. In pond Goldfish reproduction it is the ultimate case of "Survival of the Fittest".
it depends on the situation. They will if they are starving.
Goldfish are a very common species available from most pet shops and online fish sellers. Due to their popularity it will be very rare that none are in stock.

Below you will find a link to where you can buy goldfish along with information on this coldw ater fish.
Can goldfish live in heated tanks?
A goldfish is a cold water fish, so it does best when it is in cooler water. Any goldfish forced to live in a tropical fish setting will probably live, just like you can live outside when it's very hot in the summer, but it will not be the healthiest, happiest goldfish it can be, just like you would rather be in the air conditioning.
How does a goldfish survive in the wild?
In nature there are many kinds of tiny macropods, microscopic algaes and other things in the water when goldfish breed in spring under normal/wild conditions. These 'baby goldfish foods' can be purchased at most good pet shops
it is best not to mess with the temperature of the water... Goldfish like solid temperatures, it is best to keep the temperature around 75-78 degrees.
They are exothermic animals relying on the temperature (thermal energy) of the water to stay alive. Too hot and they run out of Oxygen and suffer from exhaustion and eventually die. This is because gases are more soluble in colder water. Too cold and their vital organs slow down and stop working and the fish dies. For Goldfish the best temperature is 68-72 degrees Fahrenheit.
Goldfish, are, however more active in warm water, because the heat from the water increases their metabolisms. This actually decreases their lifespan and is dangerous.
Goldfish are more active in warm water than cold.
