What i recommend is putting your food (i use frozen) in front a powerhead on the other side of the tank so it blows to where the trigger likes to hide. Also i built my own holder that keeps dry food in one spot. Melev makes one for fifteen dollars. Eheim Chimney | Melev's Reef this allows me to put food in and walk away, but the trigger still has time to go get the food before it all gets pushed into overflow or eaten by other fish.
