This is my own Drawing of Koi Fish :)
This fish mainly for decorative purposes due to its large variety of colors. Some people even believe these fishes to be lucky. I personally have these type of fishes, Taking care of these Fish is one of my stress relievers.
In this world, It doesn't matter how strong you are as a person. Everyone has their own cross to bear, and we all need some stress relievers in our life.
Have a Great Day :)
