Most Smallest Fish on Earth

The Paedocypris progenetica is officially the world's smallest fish at only 7.9mm long, that is less than 1/3 of an inch! Not only is in the smallest fish in the world, but it is also that smallest vertebrate or backboned animal in the entire world! It was discovered in the swamps on the Indonesian island of Sumatra in water that has a PH level of 3. This is about 100 times more acidic than regular rainwater!The Paedocypris progenetica is actually partially see-through, they have a reduced head skeleton, which leaves the brain completely unprotected by bone. The previous record for smallest vertebrate was held by an 8mm species of Indo Pacific Goby. This discovery was made in 2006, I wonder if this really will hold up as the world's smallest fish. What do you think?
