I really want to feed my corys, and pleco's ( and the loach I want so badly ) frozen foods and such, but my tank has good movement and the foods go all over. is there a way to keep them down on the bottom with out them going all over the place? Should I shut the pumps down for 10 minutes? do you use something to put the food in to keep it in place? help me figure this out please. I want to feed my bottom dwellers better foods then sinking pellets and disks.
