Goldfish

Other common goldfish would be best. Putting fancy goldfish in with common ones often leads to food competition and fin nipping. And as for other species of fish, its best to stick goldfish with other goldfish.

They were developed by the ancient Chinese aquarists using the process of selective breeding to be living creatures of beauty, colour, motion and interest to watch.

Not neccessarilly all feeder fish are goldfish. Feeder fish are usually those fairly small fish that are regarded as being not suitable for sale as specimens for some reason. They often are poorly coloured or deformed livebearers and other species too.

Yes, I agree with the answer above. I am sad to see the feeder goldfish they sell in such terrible conditions! My fancy goldfish were almost 10 dollars each, and the feeder goldfish were 75 cents!

If the fish can not free itself you will have to break the shell open very carefully and release the fish otherwise it will die. Then get rid of all useless rubbish in the tank. All the fish needs is some gravel on the bottom for the plants to grow in and enough light for the plants to grow, and maybe some rocks too. Then you need to follow the basic rules of fishkeeping. The minimum standards that all fish must have in order to survive.. :-1 inch of fish needs a minimum of 1 gallon of water. (a goldfish is a 10 inch fish). :- Every tank must have a permanently running 'cycled' filter. :- Every tank must also have at least 50% of its water replaced every week.

It really depends on the Betta. Like if it's a female or male. If it's a male, you could try snails or an african dwarf frog. But if it's a female Betta you have a little more variety like a second female Betta or a few neon tetras. Also though, the tank isn't really suitable for holding many fish considering it's size so be wary of your choices.

My fan tail goldfish swims upside down or wedges itself under the filter when it's constipated. I feed her the inside of a frozen pea and soon she's swimming right side up again. == == Unless it is an up-side down catfish, a fish should not swim upside down. Fish who do swim upside down are sick. It could be a swim bladder problem, a bacterial infection, a fungal infection, or constipation. Do frequent large water changes, feed less, treat for bacteria and fungus. == == If your fish swims upside down it most likely has a swimbladder disorder/disease. This happens when the swim bladder, a gas filled organ that controls the fish's bouyancy by inflating or deflating, is unable to control itself and causes the fish to either stay at the bottom of the tank, float helplessly at the top, bob-around head first at the bottom, swim on its side, or swim upsidedown. A swimbladder problem can be caused by consipation, bacterial infection, poor water quality, physical damage to the swim bladder, or physical deformity of the swim bladder. This condition is sometimes hard to treat because its often hard to diagnose the cause before its to late. The first step to take with a fish that has a swim bladder disorder is to test the water quality of your tank. It is usually a good idea to move the affected fish into a 5-10 gallon hospital tank for observation/treatment to ensure that the other fish do not become sick also. A good first act of treatment for an unknown cause of a swim bladder disorder is to try feeding the fish a shelled thawed or cooked unsalted green pea (the green pea is a laxitive and will relieve your fishes swimbladder problem if it is constipated). If this does not help you may want to start the fish on a antibacterial medication. Do frequent water changes at this time because having good water quality will offer relief for the affected fish. Also lower the tanks levels so that is is about 1/2-2 inches above the fishes dorsal fin (this reduces pressure on the swim bladder causing the fish much relief).If the fish looks swollen that is often either the beginning stages of dropsy or a sign of constipation. If dropsy is suspected than you would want to start the fish on antibacterial medicated food soon! Often fish do not recover from a bacterial infection of the swim bladder. Bacterial infections will usually result in dropsy- which is terminal.

The first thing you have to do is look after the fishes water properly. (The poison (ammonia) in the water is what has caused the fungus). The basic rules for keeping fish are:- 1 inch of fish needs a minimum of 1 gallon of water, all fish need a cycled filter running permanently and a fish tank should have at least 50% of its water changed every week. A goldfish grows to around 10 inches so it should be in a tank that holds at least 10 gallons of water (Nominally a 13 gallon tank or larger). You can get fungus cure at a pet ashop but it will do you no good at all if you don't follow the basics I have just given you and look after the fishes water properly.

A common cause of this in living goldfish is a condition known as swimbladder. The swimbladder controls buoyancy, if there's a problem with it the fish may float to the surface. You can get treatment for it at a pet shop, usually drops that you add to the water. Hope this helps!

No. I believe it is bilateral.

Wokori: They are both vertebrates.

I'm glad you asked! That is a very interesting question with a most interesting answer. The bubble-eye goldfish is a rare breed of celestial fish, lacking a proper sphincter, and thus the bubble-eye goldfish has difficulty discharging flatulence. Over time the unreleasable gas transforms into a toxic fume, which would otherwise poison and eventually kill the bubble-eye goldfish. Can you guess what happens to that toxic chemical? That's right. As the Bubble-eye goldfish grows and ages the membranous tissues beneath it's eyes fill with a mix of nitrogen, hydrogen, and carbon dioxide. In short; it's farts. It's nasty, disgusting fish farts.

No matter how much you feed them, they're going to pretend like they're still hungry. Goldfish eat like pigs. Just a small(ish) pinch 1-2 times a day is plenty. And be sure to scoop out anything they don't eat, because it will just make the tank dirtier. Whatever you do, don't overfeed. Goldfish are dirty fish in general, so the more you feed, the more they go to the bathroom, the dirtier the tank gets.

you should clean the goldfish tank once a week depends of what size tank you have and if u got a pump/impeller if you have these then ever 3-5 weeks depends on the water condition
1-2 times a week

Foliage, decaying tree bark, and maybe dung.

I have alos seen a mystery snail eat 3 feeder fish! Strange

It realy depends on the fish. I have a 32 gallon and i have tropical fish in it. So for tropical fish it is generly 1-2 inches of fish per gallon. In mine i have 3 zebera dainos,3 platies,1 rainbow shark,1 femail beta,1 glow fish, 1 cherry barb,1 albino Cory cat and, a 4 inch sucker fish. i hope that explains your anser!

Goldfish do not have hair; instead, they have scales that cover their bodies which can vary in type and colour depending on which type of goldfish you have.

Yes slice the apple pieces into smaller pieces for your goldfish to swallow it.Feed them fruits and vegetables every 2 days.

Fish are more active in Spring/Summer, feeding and growing well but falling into a state of 'hibernation' in Autumn/Winter when they stop feeding completely. So feed in spring and summer. Stop in winter and fall!

Most bags of koi food have directions on how much to feed depending on temperature. Don't overfeed or the pond water will get dirty faster.

Once the fry are free swimming and feeding well, you will see the male litterally dashing around collecting and spitting the fry back into the nest only to have them swimm back out again. Then is the time to move him before he looses the plot and eats them in frustration.

Sexing Goldfish outside of the breeding season is extremely difficult. In the breeding season males develop small white pimples (breeding tubercles) on their gill covers and along the edge of their front fins (pectoral fins). Females are generally more rounded and deeper in body shape as they fill with roe (eggs) and have a larger vent before the anal fin.
