I'm trying a new food product line by Chefzillia available at Oceans By Design. The coral food is a interesting froz. 2part process. The first part excites all the corals and fish into an absolute frenzy, and that is when you add the second part that remains in the water column for an extended period for the corals to have ample opportunity to catch/absorb the nutritious rich food. I'm working on video that shows the frenzy transformation. Amazing to witness!
