Congrates...
10" is a great size of Silver...Right before the fastest growth spurt in it's life...the next 12 months or so will see your Aro take on size and weight...
I feed my 9 incher,
4-5x per day Prawn w Hikari floater just 2-3 pieces about the size of pinky fingernail cubed and 1 stick. Then I give him small portions of Krill, Superworms, Cricket (1/8") and he catches and eats moths and Misquito hawks too when he can catch them...
