This really depends on whether you have live rock or not. If you have opted to use live rock as a filter, then allow the tank to cycle fully before adding fish. This is generally 4 weeks, but you can confirm using test kits. If you are not using liverock, but are using a canister filter or other type of filter, then put a very hearty variety in serveral days (3 is a good number of days) after having the tank fully setup and running. The only fish that are likely to survive in the first 6 weeks are Damsel fish.
if you buy it at pet-smart you get a bag with a fish that you buy and you put that in with the water for fifteen minutes, or until the water in the bag is the same temperature as the water in the tank. then you open it and let the fish go.
Don't quite get the previous edit, a 1 gallon isn't suitable for any fish. Anyway, it depends on how you are maturing your tank, are you putting it through the nitrogen cycle? This process takes around 2-6 weeks to complete, varies from tank to tank and the way you are doing it, without fish and with pure household ammonia is the quickest!
Once a tank has cycled you need to stock slowly, a few low waste producing fish first, obviously what depends on the size of your tank, and build it up slowly over the next 2 months! Adding too much too quickly will cause the tank to crash and you could end up killing your fish.
any time
about half an hour to an hour
If there is water in there...
scoop water from existing tank place fish in it and scrub tank wiith salt and rinse thouroghly put fresh water give about a day for water to be at the steady room temp. and out fish back in
Iv got a filter in mine, so i do a 40% water change everyday (that's where you take 40% of the water out and replace it with clean water) and every 5days to 1 week i put it in the spare tank while i clean its normal one, and i clean all its toys too, then stick a lamp above the tank whats just been cleaned so the water isn't too cold for it. Then when the water isn't freezing, i put it back in its old tank ^_^
Put it in a bag of water until you've finished changing the tank water.
It is important to remember to put things in a goldfish tank, even goldfish get bored. Some of my suggestions for tank decor are artificial plants and a "hidey hole" for your goldfish.
you should do a 25% water change , clean the filter , the gravel , and the tank you can put your fish in another bowl/tank
you put it in water, feed, clean it, clean the tank or what the water is in. clean the water its easy.
Yes, the bigger the tank, the bigger they will grow. Yes. The more resources given to the goldfish * more oxygenated water, * aquarium plants, * room to swim, * cleaner environments, the larger the fish will grow
Firstly, hopefully you do not have goldfish in the 'goldfish bowl' as they need at least 20 gallons for one goldfish. That being said, you can add sea shells to a tank provided that you have washed the shells clean with one part bleach to 19 parts water (1 cup of bleach to 19 cups of water), rinsed the shells very well in water, then soaked it in treated water (water that you have added Prime or Amquel to for example) before adding them to your tank.
goldfish will survive in tap water but it is best to put a bit of chlorine control in the water plus you will need a filter if you want the water and tank to stay cleaner for longer :)
No. Unless you put it in a tank with sand.
