Beginner: Clean a Goldfish Bowl
Clean a goldfish bowl
If you choose to use a goldfish bowl over an aquarium tank or outdoor pond, you will have to change the water almost daily because all goldfish in general produce a lot of waste and ammonia (see more about this topic at Nitrogen Cycle). By adding a layer of small gravel and a few living plants will help keep the water clean longer. If you decide to add an algae eater, you will need to give him space too and you will need to keep the water around 77F/25C. This might require you to buy a heater if your water temperature is to cold (see why this is not recommended at Goldfish and Algae Eaters).
To clean the water take out 50% of the goldfish bowl’s water and replace it with clean water none chlorinated water. If you are careful and don’t take a long time to do the water change, you can probably leave the goldfish in the goldfish bowl you are cleaning (see more about why at Goldfish Diseases and Goldfish Water). During this time you can scrub off any algae with a clean rag with no chemicals or detergents in it. We recommend an algae scrubber that you can get from your local pet store. But remember, a little bit of algae is a good thing (see more about this topic at Goldfish Food).

I assume they are small goldfish that you won at a fair or something. I would suggest at minimum a ten gallon tank with a filter but five goldfish will grow large and will eventually need a larger tank. You might be able to find a used 20 gallon tank on Craigslist or a good starter kit online. If you get anything smaller than ten gallons, you will need to change the water every few days. Buy an ammonia test kit and test the water. if the levels are high, do a water change.
If you have any friends that wants a goldfish or two, I’d suggest giving two of them away. A few goldfish are easy to care for but five might be difficult.
I have won five goldfish what is the best size tank I should get ahow much water shold be in it?
I know, it is a lot of work to clean the tank daily but it’s the only option if you have a small bowl. The best way to avoid that is upgrade the size of your tank. Depending on how small the goldfish are, you might be able to get away with changing the water every other day. I would buy a cheap test kit and test the ammonia levels. If the levels are good, you can go without changing the water probably for another day. best of luck
What if you do not have time to clean a tank every day?
I recommend feeding them 3-4 times a day but very small meals; just a few flakes each feeding. however, that’s not always an option since people go to school or work. If that is the case, feed it once in the morning and once when you get home. Only feed them as much food as they can eat within a minute or so. if after that time, remove any extra food.
how many times should we feed a gold fish per day
You might need to change the water more often than that but the best way to tell is by getting an ammonia test kit to check the levels in the bowl. If check it a couple times a week and if you notice that the ammonia levels are high, you should change the water. Once you figure out how many day can pass before your water gets bad, then you can change the water that often. You would be better off getting a larger tank with more water; this means less cleaning as often as a bowl. good luck
