This is what I do to my aro and I will be doing it to my 4 pbass when they get a little bigger. If you have a large tank it is easier. I stand on the second step of a ladder and I have the top of the tank open, then I throw bits of krill or shrimp into the tank. The little splash makes them think an insect just hit the water or a little fish just jumped, thats how I feed the aro and it works great, then as time goes on, get a little closer until you can just drop the food in and they will eat. Sounds like stupidity but if all the other ideas fail for you, give mine a shot, Im thinking how it would be in the wild for them.
