We also had a little exitement when some of the Tilapia started showing interest in spinners.
Unfortunately it was only one or two of them showing interest and then they would only follow (There are big schools just looking at your lure go by...)
I decided to switch to a popper and started teasing one of the big ones. I worked it very slowly past the bugger popping it pretty hard every now and then. It finally turned and started to follow, but didn't want to take. I let it lie there for a couple of seconds with the fish turning around the popper, then I suddenly worked it away from the fish pretty fast, fish turned violently and, VAS!
Tilapia on a popper, first for me!
