If that is the case then you must be doing something very very wrong. Are you keeping to the rules of fishkeeping? The basic rules are. :- 1 inch of fish needs a minimum of 1 gallon of water. Every tank needs a permanently running cycled filter. :- Every tank needs to have at least 50% of its water changed every week. . Follow the above rules and keep your fish at the temperature they need. Feed them as much as they can eat in 15 minutes morning and evening and your fish stand a chance of having a healthy life. Fail in any of the above and I can guarantee that your fish will have constant health problems.
