Kat’s Aquatics makes some of the best invertebrate food we have 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: shell development, normal molting, and overall condition. We keep the full lineup in stock here at Tropical Treasures because it is the same food we trust in our own shrimp and snail tanks.
What makes Kat’s Aquatics different
Invertebrates have very different needs from fish, and Kat’s Aquatics formulates with that in mind. Everything is copper-free, which matters enormously for shrimp and snails since even small amounts of copper can be harmful to sensitive inverts. The recipes lean on bioavailable calcium and trace minerals that support strong exoskeletons and clean, successful molts — the moments when shrimp and snails are most vulnerable. Instead of generic fish flakes repurposed for inverts, these are purpose-built blends made by aquarists who actually keep and breed shrimp.
Each supplement also has its own focus, so you can dial in exactly what your tank needs. Whether you are conditioning a breeding colony, supporting a tank after a difficult molt, or just keeping a peaceful planted setup looking its best, there is a Kat’s blend that fits the job. Hand-selected by real aquarists in Cheyenne, Wyoming. Available in-store at Tropical Treasures Wyo in Cheyenne, Wyoming. Eligible dry goods may be available for shipping throughout the Lower 48 states.
Best sellers
A few Kat’s favorites do the heavy lifting in most invert tanks. Calcium + Nutrition is the everyday mineral supplement that supports healthy molting and shell development, while Calcium + Protein adds the extra protein growing shrimp and snails need. Calcium + Immunity is formulated to support overall condition as part of a varied feeding routine, and Sweet & Savory Calcium is a tempting daily option your inverts will swarm.
For something a little different, DIY Snello Powder lets you mix up your own nutrient-rich snello at home for snails and bottom feeders, and Shrimpsicles are natural stick treats that make feeding time easy and fun. Mix and match across the range to give your cleanup crew variety throughout the week.
Great for your cleanup crew
Kat’s Aquatics is formulated for the whole invertebrate community. Neocaridina and Caridina shrimp benefit from the steady calcium and minerals that support normal molting and shell development, which is especially valuable in a breeding tank. Mystery snails, nerites, and other freshwater snails use the same calcium for shell development. Even a mixed invert tank with a little of everything is well covered — just pick the blends that match your goals and rotate them in.

If you are new to keeping inverts, a good starting point is a reliable everyday calcium supplement plus an occasional treat to keep things interesting. From there you can layer in protein for growth or an immunity-focused blend during stressful periods like cycling, water-parameter swings, or after adding new livestock. Because these foods hold together well and do not cloud the water, they are easy to dose in nano tanks and planted setups where water clarity matters.
Experienced shrimp breeders appreciate the consistency just as much. Steady, copper-free nutrition supports berried females and newly hatched shrimplets with minerals as part of a varied feeding routine. It is the kind of dependable foundation that makes a colony easier to grow out over time, which is exactly why Kat’s Aquatics has become a staple on so many invert keepers’ shelves — including ours.
Frequently asked questions
Is Kat’s Aquatics food safe for shrimp?
Yes. Every formula is copper-free and made specifically for sensitive invertebrates like shrimp and snails, so you can feed with confidence.
Why is calcium so important for inverts?
Shrimp and snails use calcium to build strong shells and exoskeletons and to molt successfully. A steady calcium source supports normal molting and shell development.
How often should I feed these supplements?
Offer small amounts a few times a week and remove anything uneaten after a few hours. Rotating different blends gives your cleanup crew balanced nutrition without overfeeding.
