I use two ways to get food to bottom fish. If you want to feed frozen foods (bloodworms, brine shrimp, etc.)you can use a turkey baster and squirt the food into the clown loaches hiding places. If using sinking foods I use a piece of intake tube or whatever kind of 2" (or so) diameter tube you have and put the food in the top and it sinks through the tube without the larger fish seeing it straight to the bottom. My clowns know this and most the time are eating straight from the bottom of the tube. This would work best if you fed the JDS on the other side of the tank while sliding the sinking food through the tube on the other side. Best of luck!
