Visitors discover a kaliedoscope of colorful fish around every corner at the Tennessee Aquarium. And one display is even more vibrant than ever right now. Check out the Asian River exhibit the next time you are in the Rivers of the World gallery inside the River Journey building. "It's my favorite exhibit," said Aquarium voluteer Fran Hiestand. "The fish are so colorful." Several people were drawn to this spot to see the denison barbs which are pictured above. They were among several species recently added to this lively display. Along with the denison barbs, brilliant rasboras, harlequin rasboras, cherry barbs, rosy barbs, three spot gouramis, giant danios and a tricolor sharkminnow are new additions. It's truly amazing to see the spectacular markings of these very active fish.
