Since I have large gravel in my tank, I found that the progold has a tendency to fall between the gravel before my goldies can get to it. I started placing a bowl in the bottom of the tank, soak the food a bit and dump it into the bowl at the bottom. My goldies go crazy when the see the bowl sitting there. But I have discovered that my goldies aren't the only ones who have discovered that the bowl means food. My flying fox and one of my hong kong plecos (bottom of the bowl) are in there for their fair share
