We just got a new silver arowana and i know its in their nature to be skittish and scared of everything which ours is- every feeding it stresses out and every time we walk in the room it stresses out- my question is how long does it take on average for an aro to settle and start eating properly- right now ours won't eat anything but crickets and even then it wont eat them when anyone is in the room and takes forever to finally eat them. We have tried bloodworms and it ignores them, what is a good food to try in which a skittish aro will most likely eat?
