Hello all. Im looking for the largest reliably measured C. mono. Not something you saw in a massive zoo display or LFS and guessed at the size. I mean actually used a ruler/measuring tape on. I ask because I see a lot of people swearing by the sizes of 20 - 24 inches, but ive never seen anything larger then 15 inches in all my many years of fish keeping. So, measure up people and let me know.
