ONLY those with perfect vision can spot the five golden koi carp fish in this fiendish puzzle.
If you enjoy brainteasers and are an animal lover, this is the illusion for you.
Along with the satisfaction you get once you solve it, this puzzle will test your eye for detail and patience.
This nature-themed image created by shows three fishermen, two in boats, and a lake full of koi carp and other fish.
Koi are often identified by their bright colors which can cover their body or appear in splotches.
There are five completely golden fish in the puzzle - can you spot them?
The bright colors of the image keep your eyes distracted with the reds and oranges of some of the fish, the blueness of the water, and the green specks from the boats and lily pads.
Perhaps the easiest golden fish to spot is the one lying in the bucket behind the fisherman on the deck.
Now you know what to look for, can you see any others?
Another can be seen among the reeds to the very left of the image.

It seems the golden koi enjoy being hidden with a third just poking out from underneath a lily pad at the top of the puzzle.
To spot the other two, you should focus on each of the boats.
One of the fish is just swimming ahead of one of the boats with its face and a small fin poking out from the bow.
Meanwhile, the second is harder to spot as it is partially obscured by the fisherman's oar in the top right-hand corner of the image.
