An aquarium fish feeder and a method of feeding fish with a fish feeder. The fish feeder includes mesh walls, a stiffening member and a suspension device. The feeder receives fish food, which is urged against a mesh wall, and the feeder is submerged in water in an aquarium. Fish feed by eating food through the mesh or by eating food that protrudes through the mesh. After the fish have eaten, the container with uneaten food may be removed to prevent fouling of the aquarium water. The stiffening member allows the feeder to be configured and held in a desired shape to allow greater access to the feeder for a greater number of fish. The suspension device permits the feeder to be suspended above the aquarium bottom.
