Thanks for all the replies. I will try some of the suggestions.

The lake is very shallow and full of weeds, and I am fishing from a bridge. I can see most of the hits.
I do get some sunfish hits as you guys suggeted, but the others are small bass (I can see them). They are about 12 long. They just attack the pink tail. They even hold on to it. But there is no hook there to grab on. If there any way to add another hook at the tail?
