I recently started to use a syringe to feed my riccordias this stuff to see what happens. I tried it once so far and observed the following: At fist they tightened up, but I could see the mouths of the ric's open up, somewhat like an anemone when it eats. A day after they were fuller and more puffed up. This has proved to be a really tricky, and trying method because these two ric's of mine are located near 5 anemones where the clowns make there home and they don't want me anywhere near them, gets to be annoying when they bite me, so I have to use some plastic tongs to hold the syringe while I use another plastic wand to press the syringe. Its like using large chop sticks.
