Has goldfish adapted over time?
There are many interesting parts in a goldfish. There are lots of fins in the gold fish. The anal fin is the fin just before the tail, and the tail is called the caudal fin too. Another one is the dorsal fin which is the single fin on top of the back, the pectoral fin which is the first forward pair of wings, and the pelvic fins which are the second ventral pair of wings. The top of the head is called the cranial. The scale is the skin of the goldfish. The fish has eyes, mouth, and nostrils also.
Goldfish live in environments which oxygen is in relatively found than us. The density of water makes it difficult for us to move fluid back in forth in the respiratory organs like we do with our lungs. That is why goldfish and other aquatic animals have special adaptations to solve these types of problems. Gills are the respiratory organ of most aquatic animals that breathe water to obtain oxygen, consisting of a filamentous structure of vascular membranes across which dissolved gases are exchanged. Instead of pumping water into and out, the animals pump water in one opening out to another making something like a stream in the organ but the animals don't use their energy to make it stop flowing then starting it on the opposite direction. Then, to make more gasses between the blood and water, it has an exchange system that exchanges gas.

I have had my goldfish for 12 years and in the last 2 years it has developed a habit of splashing with it's tail as I walk by . It does this about 2 times a day when it is hungry. If I don't feed it it will splash every time I walk by until I do feed it.
Why do goldfish do white excrete waste?
There will be a problem either with the water or the diet. My advice is to do a few large water changes taking all the proper precautions and equalising all parameters. Then I would improve the fishes diet by adding a feed of earthworms at least once a week.
How do you know when the goldfish is ready to lay eggs?
You should see that the female goldfish appears fatter than usual due to the eggs she is carrying. The male will have white spots on his front fins and gill covers and will pay the female a lot of attention chasing her around the tank or pond.
Usually a sick fish has its dorsal fin down rather than fully extended. Other things to look for are a sunken belly, any kind of whitish, stringy or fungussy (like cotton wool) stuff attached to the fishes body, mouth or fins. Scales should be laying flat smoothly with none missing. Splits in fins are another thing to warn you of problems as are whiteish spots about the size of pin pricks on the body and fins of a fish. Another thing to watch for is the way the fish swims and positions itself in the water if it seems to be struggling to either go up or down in the tank it has problems. There are heaps of other symptoms of illnes but the ones above will probably help you a little.
What do you do when a black molly has baby fish?
Your Molly will be very hungry and may be a little frightened so make sure she has been getting enough food and that she has a space in the aquarium to be on her own for a bit. Don't worry if she doesn't eat for the first couple feeding, this is normal sometimes. So with enough food and alone time your Molly will be back to her old self within a few days
How many eggs do comet fish lay?
Comet goldfish usually lay between 500-5,000 eggs. The reason why they lay so many is because goldfish eggs, and fry, have high mortality rates. Having so many eggs ensures that at least some of the goldfish fry will reach adulthood.
Why do goldfish shed their scales?
The fish has a fatal, untreatable disease called dropsey and should be euthanased. This problem is usually caused by very poor water conditions. ie polution due to insufficient water changes or poor filtration or both. To avoid this kind of thing happening you need to do at least 50% water change weekly as well as having a properly cycled filter operating in the aquarium. I hope you are also sticking to the basic rule of 1 inch of fish needs 1 gallon of water. If you are overstocked then you will need to do daily water changes of at least 20% per day as well as a large 75% one on week ends and maybe even more if you wish to avoid constant health problems with your fish.
How do you find male and female fantail goldfish?
Determining the gender of goldfish is a lot harder than people may suspect. During breeding season, the males will get what we call breeding stars on the cover of their gill plates; they look like tiny white bumps.
You might also be able to tell by their vents under their tail, but it takes a lot of practice and knowledge to easily tell them apart when it's not breeding season.
In addition, even if it is breeding season, and you have all males, or all females in your tank, it remains difficult to tell the difference as the males need a female in the tank, and vice-versa for the females so that they will show typical breeding behaviour.
yes the gold fishes eat everyday. if they are Hungary or not they tend to eat all the time..they are gluttons..but even if they are not fed they can live upto 15 days
What food should you buy for your baby goldfish?
None fatty meats like chicken breast, bits of bread and biscuit, bits of cooked vegetables like carrot, spinach etc. Insects like flies, then there are maggots and earth worms etc. It is very hard to feed a goldfish a balanced diet from your own supplies at home that is why pet shops carry Goldfish food. It is cheaper and far safer to feed your goldfish properly made food and supplement it with a few earthworms occasionally.
Why do goldfish stay still in the bottom of the tank?
Goldfish have several different fins that assist them in moving from place to place. Starting from the back, the caudal fin moves in a left to right motion to propel the fish through the water. The anal and ventral fins are for steering. A fish's pectoral fins are also used for steering, but in some fancy breeds these fins are also used for propelling the fish, such as with the Ryukin. Last but not least, the dorsal fin on the back of the fish is used for stopping. The fin is fully erect when stopped, and lower on the body when in motion. Fun fact, a goldfish cannot swim backwards.
Goldfish use their tail and fins to swim through water. To learn more, see the related link.
Do Clownfish eat goldfish flakes?
I kept a fantail goldfish and a koi together for 1.5 years. They got along fine. It may have been just my fishes' personalities but I never had a problem with those two. They were buddies. When I got them they were both about 1.5 inches long, so they were young. I rescued them from a kindergarten fishbowl.
I don't recommend keeping them together in an aquarium unless you've got lots of room or a large pond. I just donated the koi to the city aquarium because he's over 7 inches long and growing fast. The fantail has grown too, but not as dramatically.
How come some goldfish have fat stomachs?
Their are many varieties of goldfish, however goldfish with fat or potbellied stomachs are classified into the "Egg Bodied" goldfish category. Egg Bodied goldfish are their own distinct group of fancy goldfish which all have an unusually large abdomen. The most popular goldfish in this group are the Orandas, Ranchus, lionheads, and the pearl scale/Hama Nishiki.
Can ick be given to other fish?
Yes, most of the time when fish have ick, all of the fish in the tank get it.
If 1 fish in your tank has ick, treat the whole tank.
The Moors were a group of Muslim peoples, primarily of North African origin, who invaded and settled in parts of Europe, particularly the Iberian Peninsula, during the Middle Ages. Their diverse backgrounds included Berber and Arab ethnicities, which contributed to their darker skin tones compared to the predominantly lighter-skinned populations of Europe at the time. The term "Moor" has historically encompassed a wide range of peoples and cultures, and their representation has varied over the centuries, influenced by art, literature, and historical narratives.
What do you do if your Betta fish has ripped up looking fins?
Put in in by itself, and if the fins are not to tore up they will grow back, if they are to far gone the fish may get a fungus and die, whatever the fish should be removed from the tank isolated and allowed to heal or die.
Unless seroius your beta fish should look completely normal again in a few days. they heal at an exceptionally fast rate
How long can a bubble eye goldfish live for?
A ryukin can grow pretty large in body size. Because of their shape, they tend to grow tallish, and fat. It's not uncommon for them to get to a 10 inch in length including tail fins, but their girth can grow quite massive.
What temperature should water be for pregnant molly?
Keep the water at a normal temperature for mollies: 78-82° F. She'll do just fine.
No, Goldfish cannot sing.. but they communicate in some kind of way... just like ants, they communicate with antennaes,... just like singing. Goldfish Comunicate by using bogy language like signs: - Swim away quickly.... Scared - Gills are opened.... Come near!/Get away from me/danger! - Swiming around in circles.... Help me! - Gulping for air.... --- Your fish has a desease--- ... If there are other ones that are not listed here... Ask the question of tha t body language..... Thank you!
They can but they will certainly not benefit from doing so.
