You should change at least 50% of the water in your tank each week at minimum. If your tank is too small, to over-stocked, or you do not have enough filtration, then you will need to change the water more frequently.

If the Betta aquarium is properly set up with a filter, heater, substrate, plants and light then 10% water change weekly should be enough. If a Betta is in a tiny bowl/container with none of the above mentioned neccessities then the water should be changed daily.

This will depend on your tank size, the fish you have, your stocking level, and whether you over-feed your fish or not. You should check it regularly to ensure that it is operating at full output, and remember to only rinse the filter media in a bucket of tank water (the bucket should be for fish use only!)

It all depends on what water maintenance products you use. Its recommended that you change the water in the aquarium every three weeks.

Your Crawdad is a fish albeit a shellfish and needs exactly the same water quality as any other fish and the same water change regime. 1" of fish needs 1 gallon of water. 10% water changed daily is good. 50% weekly is not quite so good. Do both and you are doing great by your fish.

What kind of fresh water fish don't need a heater other than goldf fish?

It is best that all fish have a filter besides Betta fish. Betta fish don't need filters cause the filter pushes them over with their big fins. Goldfish should have a filter on there tank because they are often overfed. If you have a filter you won't have to change the water as often. The only fish that shouldn't have a filer in captivity are Betta fish.
