I prefer clove oil where possible, but a quick heavy bash to the head is preferrable to me if the fish is suffering and not going to recover. The fish doesn't know what's coming, after all, and if clove oil isn't on hand, that would be my second choice.
Euthanasia is never a pleasant topic, but keeping an animal means it's sometimes a part of it. I've had to have a cat and a dog put down too, not an easy decision to make, ever, but in both cases it was in the animals best interest.
With fish, we don't really have the luxury of having the vet push the needle, or advise on when it's time, so we have to rely on our own judgement and advice from places like this on when it might be time. Having to do it ourselves makes it tougher in some ways.
I try to let a fish pass naturally if possible, but sometimes, the suffering can drag on, and it seems more cruel to me to leave them like that.
In this case, if the fish is eating, and swimming normally, I'd probably leave it to live out its life. If it's not acting stressed, fin clamped, struggling to swim, then it's not showing signs of pain and distress that we can see, and plenty of tumours are painless in other animals.
