Crayfish are the same in their needs for clean water as all other fish. The rules are :- 1 inch of fish needs at least 1 gallon of water. :- Every tank needs to have a permanently running cycled filter. :- Every tank needs at least 50% of its water replaced every week. Keep to the above rules and your fish will stand a chance of survival. Fail in any and I can guarantee that your fish will have constant health problems and will live a shortened life span.
