Legend tells us that once upon a time there was a cache around these parts, however it was never published and the cache and cache owner are lost forever. So I thought I'd create a stunning mystery cache in the location, a cache so exciting it'll prove absolutely no challenge at all to find.
How do I find this masterly classic of a cache I hear you ask? Simple, solve the puzzle below, find the cache, sign the log and relax in the warm glow of another smiley in your stats.
Here's the puzzle ...
See this this picture of a fish? Look closely at it and answer the question below.

If the fish is yellow then the cache is located at the posted coordinates
If the fish is blue then, ah, it's not.
If the fish is red then, it's a red herring!
If the fish is any other colour, seek help.
