I sell essential oils through doTERRA international. They have a wonderful clove oil that is pure and a great oil to have around in the sad event that you have to euthanize a fish.
There are also many other oils that can safely be used with other pets such as Frankincense and Lavender. You can buy online though my site or contact me to place an order for you for those that have trouble getting to websites.
