I have had goldfish for a long time (2 years :p), at first they kept dying, but now it’s getting better, but I want to take better care of it. I now had one instead of 2, only I plan to get a bigger bowl and then 2 goldfish, how big should that bowl be. And the cleaning, how often should that actually be done, and you had to leave 1 third of dirty water in it or something. So I would like to know things like that.

Answer
Dear Marrit,
There is a lot involved in keeping fish, much more than I can quickly explain here. That is why I would like to refer you to the site below, which contains a lot of good explanations and which also has a forum where experienced people can help you with all your questions.
