These fired ceramic feeding discs are designed specifically for presenting Repashy Superfood to fish in the upper and middle levels of your aquarium. The discs come with a suction cup and hook to hold the feeder in place. The heavy feeder can also be used to provide a feeding station on the bottom of the aquarium. There are three sizes to choose from: 2″ deep (food will be about 1/4″ thick), 2″ shallow (food will be about 1/8″ thick) and 3″ shallow. Discs are sold with suction cup hooks in groups of 4, 8 or 12. There is also a starter pack of 2 discs of each size, and a 4-of-each 12 pk for the most versatility.
Here is a picture of the 4-of-each 12pk:
