How tame are your fish?

For the longest time, all my fish would scatter when I walked by the tank or
opened the lid to feed, coming back after they felt the coast was clear. Now
I'm lucky to get my finger back when dropping in food . And everytime I
walk by, they congregate by the area I drop the food in. Sometimes I can
just drop my finger in by itself and touch a few fishes, esp. the pleco, who
just sits there. The only one who is extremely cautious is my big Azureus.
