Really sorry to hear this. Frequently this happens from an uncycled tank or over feeding or lack of water changes, causing unsafe water parameters leading to the injuries / infection.
Keeping their water in perfect condition is really crucial if healing can take place.
Depending if they are deathly ill... Options could be medication, also euthanasia.
Make sure if you use real clove oil not artificial clove oil flavoring - and it is oil not alcohol which burns further and if torturous to the fish.
Keep the fish in the clove oil for a long time to be sure the fish is actually dead and not just anesthetized.
