My goldfish is dying. He is suffering, What should I do?
If you feel like your goldfish is suffering yes you should euthanize it.
You should not attempt to euthanize your fish by putting it in the freezer, which will cause it a lot of unnecessary suffering and is inhumane. Clove oil is outdated and actually suffocates the goldfish slowly. The best way to euthanize a fish is to use 1 part water to 1 part clear spirit like vodka. Then place your fish in the water mixture, which will kill the it very fast.
