xCalcium-boosting sinking disks for crustaceans and bottom-dwellers
In many tanks, maintaining calcium balance supports healthy exoskeletons, shell turnover, and steady growth for species that live near the substrate. Aquatic Foods Calcium Feeders are designed to deliver a measured, palatable source of calcium, krill, and spirulina that crustaceans and bottom-dwelling fish can readily consume. The disks sink slowly, letting shy or nocturnal feeders discover them without scattering debris. Each jar includes 25 small discs and 25 medium discs, offering flexible portions for mixed tanks, picky eaters, or staged feeding routines.
To help you keep your aquarium clean and clear, these feeders are sifted and graded to remove most dust and chips before packing. That attention to processing translates into fewer floating particulates and a tidier feeding experience for you and your aquatic life. The formula also features color enhancers designed to bring out richer hues in your crustaceans and tropical fish, turning meals into more than just nutrition—it's part of the display.
What’s inside and why it matters

How to use and best practices
- Feed sparingly—let the disks sink and distribute near the substrate for bottom-feeders
- Offer the appropriate disk size for the tank inhabitants and adjust portions as needed
- Stagger feeding over the day to support ongoing calcium intake in busy tanks
- Store sealed in a cool, dry place to maintain freshness and texture
These calcium feeders are ideal for a variety of crustaceans and bottom-dwelling tropical fish, including shrimps, snails, crabs, crayfish, hermit crabs, plecos, catfish, and other bottom dwellers.
