Got some samples from the ACA and tried it out. Every fish took to it immediately. Wasn't enough to say if it helped with growth or color but no leftovers.
I have been using Xtreme for a while now. I'm all for it. It used to be the only pellet food I fed my fish. Now I do 25% Xtreme, 25% Hikari Bio-gold, 50% Hikari gold and mix it all up in one giant mason jar.
