I figured it out!!! I use pipettes instead of tongs. I used to use tongs but feeding other frozen foods is easier with pipettes. Wish I knew how to make a head-slap!
Pipettes allow you to drop one piece of food at a time. Last night I dropped Krill in Esmeralda's mouth and while she chewed I did the same for Clayton. Also, because your hands are right there, the Betta doesn't get close.
To feed the Betta (which I do first) I barely hold the end of the pipette under water and the Betta pull the food from it or if it's something not long enough for them to pull I squirt the food on the opposite side of the tank. Then I feed the ADF and other critters while the Betta is eating or chasing the dropped food. Hope this makes sense.

They're also great for dosing ferts, Prime, etc., if you get the 5 ml size.
