A friend asked me to fish some of these up for him. After about 5 or 6 hours in Sea Serpent Grotto, Labyrinth of Onzozo and Korroloka Tunnel, I found myself with 1 coral fragment in all. Did they nerf the 'bite' rates or what? The last time I tried to fish these was back in like 2005 or 2006 and as I remember it line breaks were the bigger issue with these. I mean they were still rare but not to such extent.
