"Maybe they'll teach my BG to be aggressive,..."
------------------------------------------------
I put in 50 lbs. of Talapia a month or so ago, and the BGs and HSB both seem more aggressive. Can I purchase Pacu at a pet store? I have an 800 gal. storage tank, concrete and open top, and have been raising a few RES and roseys. Guess I'll have to add a few Pacus.
