Goldfish

Yes. I took mine from the goldfish bowl and put them into the garden pond 15 years ago and they are still there. I did notice that they grew huge tho

It depends on the goldfish.. For ones that stay small you should have at least 10 gallons.. The bigger the goldfish gets the more water it needs. Those one and two gallon bowls do not cut it..

Its really a jugment call the longer you have fish in a tank, or choose to breed fish the more knowledge you will aquire in being able to determine to some degree how old a fish, or school of fish might be,if a fish looks old it probaly is, length and width will get you somewhat close combined with a good close once over visual. If you have any fish books you can find what type of fish you have in the book and the book will tell you every thing you need to know how long the fish will get when it gets to a mature age. Some fish live a long time.

A goldfish has a memory of about 3 seconds. They aren't likely to be able to form a thought or emotion such as loneliness.

goldfish have a 3 month memory they are actually incredibly smart fish

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.

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.

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.

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. People who shop for them online are often seeking fancy varieties. Here you can find an assortment of goldfish breeds for sale. Below you will find a link to where you can buy goldfish along with information on this coldw ater fish.

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.

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

Some types actually will limit their growth to their envoirmental surroundings, i.e. Space, food availibility, etc. Some types will grow normally until a certain size is reached and then continue to grow at a slower pace until it overgrows its container. Then there are types of fish that will just grow period. These are called tankbusters.

i think that's a bit like saying if i put a baby in a shoe box would it stay that small!

im not a biologist, so maybe im wrong, but a fish isn't going to naturally stop when it runs out of room. Its going to grow to its natural size... but chances are most cramped-up fish will die before they reach this size because of lack of space, lack of food and unnatural treatment.

Always research how big your fish will get before you buy it and make sure you can cope with it... fish arent toys and they don't deserve a horrible life. :) tom

I have heard this questiion over and over and the answer is simply no. what causes fish to become stunted are the high nitrate levels associated with too small a tank, not the size. either way, purposefully stunting a fish's growth is cruel,as the fish's organs will eventually fail. if you don't have a large enough tank, don't buy the fish.

P.S. i agree with tom.

EDIT:

Basically what we all want you to know, get the biggest tank you possible can, and the least amount of fish your gut allows. I always recommend tanks 100 - 350 gallons, they are most universal. Larger tanks are for real experienced people.

If the white is inside the eye, it is probably cataracts. There really isn't anything you can do except keep him as healthy and happy as possible. They are often genetic, or sometimes are caused by infection or injury. If the white isn't inside the eye, but on the outside, it could be from toxins like ammonia and/or nitrite. They burn the skin, eyes and gills. If the tank can't balance completely they will be elevated. This can happen when a tank is kept "too clean". I know it sounds strange, but if you are removing all the water and totally cleaning it every month, it never has the chance to build a healthy beneficial bacteria balance. Changing 25% of the water every week while vacuuming the gravel is a good regimen to follow. You should never have to remove all the water unless there is a serious pollution problem or a foreign substance has gotten in the water. If you are finding a lot of crud in the gravel, it means you are overfeeding. (Very common problem, I overfeed sometimes too.) If he has a hard time finding food, it is easy to overfeed because you will want the fish to get enough. Just do the best you can. They do have a sense of smell, so he can find it when he needs to. Feed sinking pellets if you don't already. Pellets come in many different sizes. Get one that fits in his mouth. He can find them before they disintegrate in the gravel and there will be less waste that way. I always recommend the sinking kind instead of floating pellets because goldfish suck in too much air if they are getting the food from the top. It can cause fatal indigestion.

If it were my fish and it looks like a outer eye infection, I would try cutting back on food and add aquarium salt to the tank. Use uniodized pure salt. You can buy it at local fish stores. Put in 1/2 teaspoon per gallon. When you make water changes, put back enough salt to treat the water replaced. For instance, your water changes are about 3 gallons, so you will add back 1.5 teaspoons every time. The salt helps the fish fight infection and it can also help kill the cause of infection. It is always best to avoid medicine when ever you can. Especially in chronic cases, hope this helps, i had a fish that lost both its eyes, looks horrid.

it is to get the food before it all gets eaten and also survive on its own without getting eaten by other animals

It can't be done. Goldies get huge unless they are the facy kind. Try a pond or get five in a thirty gallon.

That all depends on what is dirtying it in the first place. If you mean strip down and clean properly then any none abrasive cleaner will do the job provided you scrub all traces of the cleaner away before using the tank. If on the other hand you are refering to algae on the face of the tank then any of the glass cleaning equipment/scrapers sold in pets shops for that purpose should do the job. The new acrylics used are just about as hard as glass and should not scratch if you use sensible scrubbers.

It can be either these days due to some intensive breeding schemes, but it is typically the case that females have shorter finnage and duller colours (but as i said earlier this isn't always the case these days- your best bet would be to take a photo and ask at you local fish specialist

The amount of sand depends upon the design of your waterscape. I always have at least 3 inches of sand at the back and slope the substrate towards at least 1 inch deep at the front of the tank.

it is until they have sex then they forget everything.

A goldfish's gender will be very hard to determine before the goldfish is three years old. After this point, the male will develop little white pimple-looking things on his gills. These are called breeding stars. A female's fins will be more rounded and her tail will be convex.

Probably because its water is putrid. My advice is to do a water change ASAP. Then follow the basic rules for keeping fish. The fundamental rules for keeping any kind of fish are :- 1 inch of fish needs a minimum of 1 gallon of water. (more is much better) :- Every tank needs a permanently running cycled filter (it neutralises ammonia) :- Every tank needs at least 50% of its water to be replaced every week. (Keeps excess nitrate levels low) If you keep to the above rules your fish may stand a chance of survival. If you don't keep them I can guarantee that you will constantly have problems with your fishes health.

It probably means the fish is badly damaged and is dying. Please do a water change ASAP. Bad water is the commonest cause of death in goldfish. In order to keep fish sucessfully there are a few basic rules one MUST observe. They are :- 1 inch of fish needs at least 1 gallon of water. Every tank must have a permanently running 'cycled' filter. :- Every tank must have at least 50% of its water replaced every week..

Spawning gold fish are very active in backyard ponds.

They will "flash" - show their bellies, and chase each other around the pond.

When they go to lay their eggs you will see the females hovering on the bottom of the pond liner, and the males come over them, spreading their silt to fertilize the eggs.

Having goldfish spawn in a backyard pond is very exciting. To ensure that some of the newly hatched fry live to maturity and are not eaten by the adults in the pond, have some aquatic plants in the pond. I had great success with the hairy roots of water hyacinth.
