Johnny B. Goode Posted July 16, 2021 Share Posted July 16, 2021 I've done some research and it seems a lot of people say Congo tetra are the largest. I've seen some pretty big Congo tetra, but it seems like Buenos Aires tetra get bigger. Are there any tetra out there bigger than the Congo or Buenos Aries? Also are pink tail chalceus considered tetra? Link to comment Share on other sites More sharing options...
