Baitfish surface action

Haven't launched from Changi Boardwalk for some time so I decided to head there this morning. Was on the water by sunrise and proceeded to the fishing spot. I had bought some plastics again to try and this one was a fluorescent yellow twin tail plastic. I just wanted to try if the fish would chomp on such a 'loud' colour plastic.

I cast towards the rocks and slowly worked it down the rocky face to the bottom. On my 2nd cast, a fish grabbed the lure and I quickly reeled it in. It was a small Orange-Spotted Grouper and was released. Not too bad, only the 2nd cast of the day and I'm already on the board.

45mins later, another Orange-Spotted Grouper climbed onto the plastic lure as I was twitching it back. It seems that the 'loud' colour doesn't really put them off. I'm guessing the dancing twin tails were too enticing for the fish to not take a crack at it! This Grouper was released as well.

After that, it all went quiet. I changed to a few other plastic lures but nothing was interested. Then just as I was getting ready to head back, I heard some splashing sound behind me. I turned the kayak around to witness an extraordinary sight. The splashing was made by some baitfish and it was everywhere. I couldn't really see the baitfish but the splashes just kept on going!

So I decided to stick around longer and casted my plastic lures in and around the splashes. After 15mins or so of casting, nothing was interested so I called it a day just before noon and headed back home for post kayak fishing cleaning.....
