Siamese twin fish conjoined at the stomach

It is so rare that you would think Siamese twin fish attached at the stomach would never survive.

But at eight months old, these two Nile Tilapia fish in Thailand have found the perfect way to cope with life upside down ... or the right way up if you're the lucky twin.
The bigger fish protects its smaller sibling on the bottom, while it in turn looks for food.
