Goldfish

That depends on the type of extension. If the scales are sticking out like a rasp then the fish has a fatal disease called Dropsy. If the fish is just getting chubby it could be due to one or more of many things from constipation through to full of ova (eggs) and ready to spawn.

A goldfish may not physically explode if over-fed, or if too much air becomes trapped in their swim bladder as they are more likely to die from constipation or impaction before they could explode

yes, foot sizes tend to grow faster than you would normally think, this can be caused by walking more often, walking may regulate your foot size over night, foot sizes can usually grow 3-5 sizes over night.

Yes they do. Well, at least some do. They also eat meal-worms which really aren't worms.

They are spawning. The white dots just indicate the male is ready to spawn.

Multicellular.

Try to get the fish to eat a pea.

A three inch might be 1year old will it depends on the fish what kind of fish.

fighting fish can be in temp. 70 - 80 no higher or lower and use tap water do not use bottle water fish live longer with tap water I had made that mistake by using bottle water fish did not live to long tap water fish lived over two years also if your home is warm you don't need to have a heater room temp. is fine for fighting fish If you live in a tropical, warm place like Singapore or Jakarta then no heating is needed! If you live somewhere colder then try buying a heater. Don't buy an oxygenator though it's a waste of money since they don't take air from the water but from air.

My Bettas can live in either warm or cold water but recently I noticed that when I put a flat heater in the tank he would stay snugged against it.

Depends on the age. Average memory for under 6 is perhaps around two weeks. for 6+ perhaps a year. Important times will stick for an even longer time though.

Please remember the rule '1 inch of fish needs 1 gallon of water'. Some plastics are not safe because they can release deadly chemicals into the water. If your plastic container is certified safe for containing human foodstuffs/water and it is large enough to contain the fish you wish to keep in it then it should be OK

You could use the name of someone you know as the name for your goldfish or you could go for more of a comedy name such as a small goldfish called Jaws, or one called Mr Fish. In the end its your goldfish so you can name it whatever you want. Hope i helped

Bettas lay from 60 - 500 eggs and if ur not careful all of them could dye from the female eating them! They won't all live , either way. So the most reasonable amount would be...............5 - 20. That is still alot but i have fry in my bettas bubble nest , and i see tons of fry so my guess is theres about 50 living in there but , they might dye while im sleeping or away from home because they might come out of the bubble nest [when there old anough] , [ which is about 2 weeks] and the male might eat them , i might end up with 0 out of 500 , so u never know what might happen

The only time a goldfish is eaten by another goldfish is when the parents breed and they have eggs.The eggs hatch then the parents eat them because they mistake them for lava or something.if ur fully grown gold fish is eating another fully grown golfish then its not a goldfish at all!!!!!!!!CHECK FOR THE BREED in other cases.

Many people believe so, but it has recently been challenged by the Myth Busters, who were actually able to train their gold fish, which would prove that they indeed have memories longer than 3 seconds.

Theoretically, the smallest time measurement possible is one Planck time, around 5 x 10-44 seconds.

The shortest time interval measured so far is around 12 attoseconds (approximately 10-17 s).

Just because you see your goldfish picking up gravel in its mouth does not mean the goldfish is actually swallowing gravel. In all probability the fish is simply rolling the gravel around and sucking the algae and whatever else is attached to it and eating that.

Ask an expert. It could be a sign that your gold-fish is sick. Never go on wiki-answers for a medical problem. Its not a good idea.

Treatment for ich is fairly simple and you can use a number of different chemicals, but the most common three are copper sulfate, malachite green and bromthymol blue. Each has its own dosage instructions, and using all three together is also highly effective. Simply read the instructions that come with any of these products, and it should treat the ich.

Yes!

In addition:

Yes, gold fish are quiet, although some of them like to jump or splash, which isn't very noisy. However, the equipment used to aerate the aquarium can be noisy, but it's usually a "white noise", one that is continual and can be ignored or people get used to hearing it because it is always on.

Not neccessarilly. There are some very well bred fancies that are slow to colour up.

It is definitely NOT OK to keep a Black Moor in a fish bowl if you wish it to live and grow. Fancy Goldfish grow into large fish of around 10 inches or so in about 12 to 18 months. They should be kept in a properly filtered planted large aquarium. (If not a pond) The basic fish keepers rule is 1 inch of fish needs at least 1 gallon of water. Taking into consideration that a fish tank is normally filled to within 1 inch of the top and also has a couple of inches of gravel on the bottom to grow plants in, a 15 gallon (nominal) tank would only contain about 10 to 12 gallons of water. That means a Black Moor should be in a tank with a minimum (nominal) size of 15 gallons not a bowl. Actualy when you think about it, no fish should ever be kept in a tiny container like a fish bowl it is cruel.

They use everything they have evolved to use to help them hunt for food. In the case of Bettas, they hide amongst the floating (and other) plants and strike suddenly thereby surprising their prey.
