I am having serious issues with this fish, I am 0/??,??? and have been trying for well over 2 months (Started posting complaints on various forums on Oct 1). I have gone through over 4 stacks of pillbugs, 3-6 stacks of rat tails, over 10 stacks of lug worms, and have even lost a sinking minnow or two. I have put in hundreds of real life hours attempting to catch this fish and all I have to show for it is a few hundred thousand gil worth of Silver Sharks. I have fished both during the suggested open window (6am-6pm fair weather) using all of the suggested baits, and have even fished day and night, all forms of weather. I have similar spec gear as the OP (aopprox 300/290), but have read and seen screenshots of people catching it on much lower spec gear right off the bat.

I'm not sure what the drop rate on this fish, but it feels like something is amiss. Something fishy.
