I have a 75-gallon tank and clean out about 10 gallons every week. Since yours is an 18 gallon tank, I would start with cleaning it every two weeks by siphoning the substrate and removing and replacing 7 gallons.
If your water looks dirty try changing 5 gallons every week. But I think you will be good with the two week option.

How often do you have to clean out a goldfish without a filter?
Every Second! Gold Fish are Very messy and need a filter to keep them alive. I suggest you put your Goldfish in a pond. Make sure there is more than one, Goldfish have friends just like you and me. Or you could get a 20 gallon tank (the tank has to be big enough so goldfish can grow up to 10 inches long WITH a filter. okay long story short, one inch per fish needs at least a gallon!

If a goldfish is living in a bowl and loses the colour of its tail does that mean its going to die?
Not neccessarilly. You probably need to change its water more often and if possible get a fish tank (aquarium) to put it in. Bowls are not the best containers for goldfish.
Why dont goldfish breed in a home aquarium?
Most common Goldfish are pond fish and are not really suited to life in an aquarium. They need to get up speed in their mating chases and they jump out of the water as they spawn. I guess if your tank (Aquarium) was big enough for them to do this they could spawn in there. Slower, poor swimming types of fancy goldfish like Black Moores and Lionheads etc are often spawned in aquaria but these tanks are usually a minimum size of 6 foot x 2ft x 2ft.
