What to dp with torn lookin fins on guppies?

Answer 1

If a fishes fins are disintegrating, the water is bad and needs replacing ASAP. Please read and follow the basic fishkeeping rules. The rules are. :- 1 inch of fish needs at least 1 gallon of water but more is better. :- Every tank needs a permanently running cycled filter. :- Every tank needs at least 50% of its water replaced every week.Follow the rules and you stand a chance of keeping fish successfully. Miss out on any of them, and I can guarantee that your fish will have constant health problems.
