Kat's Aquatics

Kat's Aquatics makes some of the best invertebrate food we've found — copper-free calcium tablets, mineral supplements, and specialty treats designed specifically for freshwater shrimp, snails, and other inverts. Every formula is built around what your cleanup crew actually needs to thrive: strong shells, successful molts, healthy color, and steady growth.

We stock the full Kat's Aquatics lineup we trust in our own tanks, including Calcium + Nutrition, Calcium + Protein, Calcium + Immunity, Sweet & Savory Calcium, DIY Snello Powder, and Shrimpsicles. Whether you're keeping Neocaridina, Caridina, mystery snails, nerites, or a mixed invert tank, there's a Kat's blend that fits.

Hand-selected by real aquarists, shipped fast from Cheyenne, Wyoming to all 48 states.
