Goldfish

How can a fish be a"cold water tropical fish"? "Tropical fish" means the fish come from tropical waters and do not do well (In some cases die) if kept in water that is too cold for them. Goldfish are Coldwater fish and need their water around 50F to 65F. So no, they will not do well in water that is constantly between 70F and 80F where most Tropical fish need their water to be.

Feed a Queen angelfish many small portions of food throughout the day instead of just one or two big meals.

goldfish do not have eyelids therefore they cannot blink.
No.

I don't know if goldfish (or any species of fish) actually feals fear as we do (as in anticipation) but they certainly do have an immediate response to any kind of threat. They hide and know how to take cover from above attack from birds etc they also know when and how to hide in plants, branches, holes etc when being hunted by predatory fish too. So to answer your question. I would say goldfish are afraid of attack both from the air and in the water by any kind of predator that would like to eat them.

No, a Koi is a carp. It comes from the Japanese word Nishikigoi which literally means 'coloured carp'.

White particles on fishes' fins indicate fungal growth. It should be treated with fish medicines immediately or it may spread.

You should have a thermostatically controlled aquarium heater, and a good thermometer to monitor the temperature.

Although they are sold, don't use the type of thermometer that you stick to the glass; that doesn't give you an accurate temperature. Use one that goes in the tank itself.

For tropical fish, I have had the best success with the temperature about 75-78 degrees F.

Well to start, the goldfish has two eyes, two nostrils, two gill covers, and a mouth. Then comes the two major parts- the head and abdomen. And lastly their are the fins: the pectorals, the pelvic fins, the caudle fin(s), the anal fins, and the dorsal fin.

Under normal conditions goldfish spawn once each year during spring.

Even a small amount of alcohol in a fishes water will effect it badly and probably kill it. No they don't get drunk they simply die.

Yes they are different variations/varieties of the same species.

Yes, bettas should go to the surface for air. They are air breathers. They have an organ, the lybrinth, that is very lung like. They breath in air from the surface. Their gills do not work like other fish. If they can not get to the surface for air, they die. Of corse yes their gills are different from other fish so that is why a Betta fish has to be going up to the surface to get air or else they die.

because they use there tail to swim, and they don't have a tail on the front so they cant swim backwards.

This is probably just a natural color change. This is common in goldfish. If you notice any strange behavior, take it to the vet.

I always think one looks lonely. If you have two, and are lucky your goldfish might breed Babies! Anyway a collection is much better than two because they might breed more!

Neko means "cat" in Japanese... the word is rooted in Japanese history, culture, language, manga and anime: http://www.youtube.com/watch?v=kMvGj2R_dQI

Over the past decade, the use of this word has been evolving and adapting to imply a global "catgirl" phenomenon -- namely humans "dressing up cat" in real life. Evidence of this can be found in Japanese cosplay http://www.jbox.com/PRODUCT/NET067, European catgirl forums such as http://www.catgirls.org.uk/ and virtual online communities as depicted on the blog Virtual Neko in Second Life: http://virtualneko.com

Nekomimi: the Japanese term for catgirls, literally meaning "cat ears." A catgirl is a person who dresses up (in real life, or in online virtual communities) with ears, a tail, and sometimes additional accoutrements such as paw gloves and boots.

Nekomusume: this sometimes also applies to catgirls (though less often), and literally means "cat daughter."

Give it more fresh water feed it or it is so darn sick it just dies .......goodluck.

Yes. Aslong as the gold fish (coldwater fish) and the pleco (warm water fish) do not go into one extreme or the other on the temperature scale. Your plecostomus will look like it is eating your goldfish if it doesn't get enough food.

Goldfish are very gentle and low mantinance pets. They get along with each other fine and are usually not the fish that will fight. (This does make them an easy target, only place goldfish with goldfish)

There is a large variety of goldfish to choose from-fancy, black colored ones, large eyed ones. However, the "fancier" the fish, the more the life span decreases and mantinance increases.

To some it all up, goldfish are excellent first time pets and are great for someone of any age!

No, it will make due with what is left.

Umm I disagree Most fish i have observed had no trouble regrowing fins when damaged or taken off completely. In good conditions they shouldn't have this problem but if it's a disease or environmental problem then it won't grow back until conditions are repaired and the other fins may fall victim to the same fate. Occasionally the fin won't grow back for unknown reasons but generally the fish usually do okay with a missing fin as long as it's in a goldfish only tank. Check for fin rot and keep that tank as clean as possible for a while to give the best chance at regrowth.

Goldfish can only live with other goldfish. I know this is a rather sad, depressing thing, but I will remind you that there are lots of other goldfish that are pretty and there's a wide variety of them. You may notice that goldfish tanks are usually a bit bare, because only goldfish can live there. Tropical fish don't simply work out with goldfish, because of the temperature and really because they aren't supposed to live with each other in the wild anyway.

Though it's not a fish, if you really want to put some other sea creatures in your tank, I suggest to put sea snails. It's really the only other sea creature you can put in with goldfish, in my opinion. But be careful, snails can be a bit dirty!
