Sorry guys I'm new to this what's HSB stand for? I was thinking Tilopia would not be good for 3-4 inch bass rather I might wait until my second year. As far as feeders are concern I have 3 hanging out there now but may pull them latter and replace them with one on my dock....would rather not tempt the bass with getting passive and not over feed. I have a good bloom and plan to keep it until June.
