My silvers and green as well as jar do not care for me - swim away for sure (my ex Jar used to beg for food though). Note they are all fairly young, less than year old
Arapaimas are friendly and begging for food (since the begining... just wiggle finger in front of the tank). The big one does not beg but does follows me around the tank,
Bichir does not care either way (less than year old) that is does not run away nor comes begging for food.
Marble pims are too young to tell though so far they tend to swim away when approached.
In general, the fishes that i had for long time (RTCs, gars and sole Oscar) always come to the side of the glass if i stand next to it. Checking out whether i have food no doubt.
