The feeder rings are a little large for a smaller aquarium like mine (3 gallons) but they still work well. The blades are positioned on the side of the teat so they are vertical to the tank wall. My Betta can't hang on to them because they are vertical. They should be perpendicular to the teat so the fish can rest on or dangle underneath. Spring. They make the tank more interesting.
