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.

∙ 16y agoIt depands what type of fish but i know that if you have a betta fish you should change it's water every 2 weeks cause if you change it every week then the betta fish will get stressed and when betta fish get stressed they die. Well i hope this anwers your question.

∙ 14y agoIf 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.

∙ 11y agoThis 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!)

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.
