Goldfish

That all depends on what is dirtying it in the first place. If you mean strip down and clean properly then any none abrasive cleaner will do the job provided you scrub all traces of the cleaner away before using the tank. If on the other hand you are refering to algae on the face of the tank then any of the glass cleaning equipment/scrapers sold in pets shops for that purpose should do the job. The new acrylics used are just about as hard as glass and should not scratch if you use sensible scrubbers.

It can be either these days due to some intensive breeding schemes, but it is typically the case that females have shorter finnage and duller colours (but as i said earlier this isn't always the case these days- your best bet would be to take a photo and ask at you local fish specialist

The amount of sand depends upon the design of your waterscape. I always have at least 3 inches of sand at the back and slope the substrate towards at least 1 inch deep at the front of the tank.

it is until they have sex then they forget everything.

A goldfish's gender will be very hard to determine before the goldfish is three years old. After this point, the male will develop little white pimple-looking things on his gills. These are called breeding stars. A female's fins will be more rounded and her tail will be convex.

Probably because its water is putrid. My advice is to do a water change ASAP. Then follow the basic rules for keeping fish. The fundamental rules for keeping any kind of fish are :- 1 inch of fish needs a minimum of 1 gallon of water. (more is much better) :- Every tank needs a permanently running cycled filter (it neutralises ammonia) :- Every tank needs at least 50% of its water to be replaced every week. (Keeps excess nitrate levels low) If you keep to the above rules your fish may stand a chance of survival. If you don't keep them I can guarantee that you will constantly have problems with your fishes health.

It probably means the fish is badly damaged and is dying. Please do a water change ASAP. Bad water is the commonest cause of death in goldfish. In order to keep fish sucessfully there are a few basic rules one MUST observe. They are :- 1 inch of fish needs at least 1 gallon of water. Every tank must have a permanently running 'cycled' filter. :- Every tank must have at least 50% of its water replaced every week..

Spawning gold fish are very active in backyard ponds.

They will "flash" - show their bellies, and chase each other around the pond.

When they go to lay their eggs you will see the females hovering on the bottom of the pond liner, and the males come over them, spreading their silt to fertilize the eggs.

Having goldfish spawn in a backyard pond is very exciting. To ensure that some of the newly hatched fry live to maturity and are not eaten by the adults in the pond, have some aquatic plants in the pond. I had great success with the hairy roots of water hyacinth.

Never. You should change the water a few times a week if the bowl is not filtered, but do't completely clean the blwl or wyou will destroy the benifical bacteria that converts ammonia and nitrite to nitrate and o2

Goldfish NEED 20 gallons for the first fish and an additional 10 gallons per additional goldfish. So for 3 goldfish you NEED a 40 gallon aquarium with A LOT of filtration.

Your 3 goldfish will be dead soon due to both ammonia poisoning and lack of oxygen.

Since goldfish have primitive gills, they require A LOT of dissolved oxygen in the water. Hence why they do better in unheated aquariums because cold water holds more dissolved oxygen then warm water does.

You need to clean that bowl like 3 times a day. It is cruelty to keep them in there. Goldfish are America's number 1 mistreated and abused pet because people cram them in bowls. When properly cared for goldfish have lifespans of 30 yrs and grow 8-24 inches depending on variety. I have personally seen 14 inch black moors and have a picture of a 15 inch red oranda.

yes they can give your pet fish bread. i tried it with my goldfish and it stayed alive for a month and half. the type of bread you can give you pet fish is white bread. you cannot give it the edge of the bread.

The sexual dimorphism of a goldfish can only be observed when the fish are in breeding condition (in Springtime) when the adult males develop white spots on their gill plates and sometimes the pectoral fins too. The females just get chubbier around the stomach area.

Goldfish jump out of the water for a variety of different reasons. Some gold fish need more oxygen than what is in their water for example.

Leaving a dead goldfish in your tank will boost ammonia levels.. You dont want ammonia in your tank. It rapidly kills fish

Damage to the fins is the first sign of bad (putrid)water. The fish will get very sick with gill and scale damage next and if you do nothing the fish will die. You urgently need to do a few major (at least 70%) water changes ASAP. Goldfish need a minimum of 1 gallon of water per 1 inch of body length. Even given a nicely set up, properly filtered, planted, well lit aquarium, they should also have at least 50% of their water replaced each week.

Depending on the type of goldfish they can be anywhere from 6-12 inches long.

The same as role as lungs, to get oxygen. Only because there is little oxygen in the water the gills have lots of filinents with blood in counter-flow to the water such to maximise surface area and maintain a constant diffusion gradient for the best possible efficiency.

White spots on a goldfishes gills indicate that it is a male and in breeding condition. If the spots are on the body/fins etc it is usually the disease Ich otherwise known as white spot. This can be cured very easily by using one of several proprietory medications available from most pet shops.

As long as you have a filter and have treated the water with the correct amount of treatment it should only be a minute before it is safe to put it in, If you just have a filter and don't treat the water wait 24 hours if you can.

On people bummy bummy bum bum's and then people poo them out. :) thanks! I hope i have helped you :)

Well it is a very good idea to have a lot of variety in your goldfish's diet. I feed my goldfish a combo of flakes and pellets (the pellets are available at the link posted below) and that seems to work very well. Along with the flakes and pellets I like to treat my goldfish with any of the following: freeze-dried krill, freeze-dried tubi-fex worms, live or freeze-dried brine shrimp, frozen daphnia, freeze dried or frozen bloodworms,(another option is to cultivate your own mosquito larva at your home by laying out a shallow dish of water, also another option is to feed your goldfish cleaned/chopped up earthworm). Since goldfish are omnivoures they also enjoy fresh fruits and veggies: watermellon, orange slices,bannana, deshelled green peas, and spinach. Goldfish will also like being able to do some natural grazing in your aquarium if you are willing to grow duckweed and elodea. Hope this helps :)

once a day, only as much as they can eat in 5 mins. scoop out whatever is left with a net and adjust your next feeding accordingly

They eat themselves on a dailybasis for lunch,dinner, and breakfast..it science

if your fish appears to be scratching itself against other objects, or keeping to the corner, chances are that is is infected with "ick." it is also known as Ichthyophthirius. another sign of ick is that small white specks are visible on the body of the fish. it can also be visible on the fins. since ick is a parasite, it is easily cured by ick treatment that can be found in pet stores. this is a fairly common situation.
