I keep an old turkey baster next to my little fish bowl. Every few days I will use it to suck out some water and the dirts accumulated on the bottom of the tank and feed my plants. Then I can replace a cup or two of clean, airated waer into the bowl, reducing my need to change the whole fishbowl and feeding my houseplants at the same time!
Great for kids with a 'first time pet fish' too!

Recently a friend gave me two large gold fish they didn't want anymore. The one kept swimming belly-up (upside down). I was told it was a sign she was going to die soon. I couldn't take it watching her struggle! What it is, is a sign of infection and it affects their balance and buoyancy. It can't be cured.
But, I remembered an old, old remedy! I did it and it worked! I gave her early sweet peas. I smushed them between my fingers and put them in the tank. She ate them and after 1 hour she was swimming right side up like nothing. So, each day I feed her the smushed peas towards evening. In the morning she gets her regular fish food. Now, she swims with grace and beauty!
Remember it is not a cure, because there is no known cure for this.
Response to Question:
I used sweet peas from a can. You have to mush them up. But, you can't use a lot maybe 7-8 peas only. But, I did forget to mention this also means you have to clean your tank more often. JJ
My 2 year old loves fish so we set up a 10 gallon tank that we had found on the street and went to the pet store. We only buy the goldfish that are on sale (3 for $3), because then if they die, I can replace one no problem, and my son has no idea that one has died. They all look the same and do the same job as fish that cost so much more! He loves them, that is all that matters.

Here are questions related to Caring For Goldfish.
I bought my grandson "a" as in one, goldfish from Walmart the day before Easter (as in end of April). Now it has had its 2nd load of babies. 4wks ago it had 10 and now on July 4th we found 16 new ones. My grandson is now in love with his 26 babies. How is she doing this on her own? Will she keep doing it? The fish's name is Easter Fish. Thanks.
Just make sure this is a goldfish because this picture does not look like a goldfish it looks like a molly check it out! Then look for a new aquarium for the big family.....

Do goldfish eat their young? How long do they stay pregnant?
