This fin trimming was done to my asian arowana
A bit of cosmetic surgery is sometimes needed to help your fish look and function its best. At times it is done to help fix a visual issue with the fish and at others it is done to repair damage.
Typically this is done on larger fish though, as their visual traits are much more easily seen. So any imperfection is clearly visible.
I am not saying that you should do this, but rather simply showing you how I did it.
The dosing is as follows: 0.5ml clove oil for every gallon of water.
The clove oil is specifically: Eugenia Caryophyllata
