Goldfish

Give your fish 5 to 10 minutes to eat, then remove all uneaten food with a net

Goldfish die in cold water because they are not used to the water tempurture. But if you put the fish in a bag and set the bagin the cold water the water in the bag and in the tank will be come the same tempurture.

Koi have barbels on their bottom lips (whisker-like projections) and goldfish do not

It doesn't matter what tank they are in, it is the food you feed the fish.

Simply put, they will die. Goldfish are coldwater fish and if their water gets too warm, their metabolism speeds up. Their bodies then demand more oxygen for them to survive. The warmer water is, the less oxygen it can contain, so coldwater fish simple die from lack of oxygen in warm water.

Goldfish can eat cooked de-shelled peas, cooked & finely chopped green beans, lightly cooked spinach, raw romaine lettuce on a veggie clip, raw zucchini (but not the skin), and they even like peeled, de-seeded & finely chopped orange every now & then.

Hi,

The Fighter fish (Siamese Fighting fish) always likes to stay alone and if some other fishes are added it will start attack or feel depressed which affects its health.

But zebra fish is a good choice to keep with fighter fish as it swims so fast fighter fish cant reach it at any moment.

Gold fish - is a wrong choice as it has flowing fins which makes fighter fish to attack it willingly...

No! they swim around! they are too dumb to exercise

They sure can. It's quite rare though, and only happens when there's something disgusting in the tank (Dead fish) or if the water conditions are bad enough.

Their form of vomit is a white substance that they eject from their rear, and it lingers in the water for a while before being sucked up by the filter or settling on the bottom.

Once again, this shouldn't happen often.

Of course they can. Whether you're allowed to put them in the lake is a different matter, and I guess it depends what else is in the lake. But yes, they can survive and live in lakes.
yes because it is freshwater fish

the gold kind??
A gold fish is the result of a 1000 years of domesticating by the Chinese mainly during the tang dynasty of the Prussian carp carp which can only be found in China, and are still the goldfish closest relatives. All goldfish are in the family cyprinidae commonly known as the carp family, which en-composes carp, koi, goldfish, the true minnow, and barbs. It is the largest freshwater fish family containing over 2,400 species. There are over 200 different types of goldfish alone, due to the lucrative aquarium hobby.

Goldfish do not need their tank light on for more than 6 hours. Unless you have a lot of live plants in your tank, leaving the light on for a long time will result in an increase in algae in your tank. If you begin to see an algae bloom, then you're best to leave the light off for several days.

They are not that unhealthy but there are better foods.

My Fantail Goldfish did that alot the first time I got him. I think it might be that they need to relax or they might be scared.

Well, if you love your Betta fish, then it should live by itself. But if you add another Betta to your current Betta fish's tank, then they will start a fight because Betta Fish are Siamese fighting fish and if one Betta is in contact of another Betta, the possible reason would be a fight between them two.

Yes they will be happy because they can sleep in the plants and on the gravel.But the fish tank should be large for the fish so it has more room.I would get a large fish tank at petco they are a good price and work GREAT.

Males are slender,and are larger than the females about 2 times larger, the females look a little like a platy their fins are much smaller than a males. You can keep female bettas togeather, when you buy a male betta the males are generally alone sitting on a shelf in a small container that you would select or pick from.

I wouldn't recommend putting more than one or two. 28 liters is not that big. Goldfish are very dirty fish and need a large tank and a good filter. Te smallest tank I would put goldfish in is 40 liters (10 Gallons). Even that is pushing it.

A goldfish has about 1,500 bones inside of it.

He jizzed on himself.

no i have two in with mine and they all get on

Particles (either of algae, bacteria, or waste) that cloud the water are too small for most conventional filter pads to collect, as they are more intended for larger waste. First one must determine the root cause of the cloudiness to properly treat the condition. Easiest way is to determine color, length of tank operation, recent changes to decor, inhabitants or other factors.

This depends on the size of your tank. They can grow as large as ten inches in a pond. I purchased a feeder golfish 8 years ago and today in my ten gallon tank she is around 5 inches.

I am guessing that you mean a Plecostomus. The answer is NO. Each of the species needs totally different conditions. Goldfish are cold water fish and suffer when the temperature goes over 75F. Plecostomus are tropical fish and suffer when the temperature goes below 75F. They will both survive for a while in one anothers parameters but eventually they will die from living in the wrong conditions.
