How old would you say a 8-12" silver arowana is. How large will they be in 6-months from now. I feed them twice a day. (krill, earth worms and occasionally minnows).
 
Probably about nine months old, though depending on water quality and diet it could be anywhere from 6 to 12 months old. Figure on about an inch and a half of growth per month on average. It will likely be about 18-20" but 24" could be a possibility.
