Tropical fish owners may think that the tiny, colorful guppy must be the smallest fish on earth. But there’s a fish that’s even smaller than the guppy, and its name sounds almost the same, the goby.
The tiny goby, a very rare fish, lives in lakes in the Philippines. Even the full-grown adult gobies, which are transparent, are never more than a half-inch long, and most are only about a quarter-inch long.
It would take about 8,500 gobies to weigh just one ounce!
