you shoulda saw that coming, i've seen 14" rtc eat 20" aro's. its like they can almost eat anything double its size. at my lfs, they had a huge ass tank with 1 2ft rtc and a 30" aro, 30" aro got eatin but it took almost a week for the aro to be completly gone. the tail was stickin out of its mouth til it went all the way down lol. i want a tsn but i want a baby, half the size of all my fish or even smaller.
