I do a water change every two weeks at which time I chang out the stones and the cuttlefish bones. I just added new shrimp but the one that was in my 30-gallon tank (a freebee that got caught in the net at the pet store), is HUGE. It pays to give your invertebrates calcium rich foods along with something like these rocks and cuttlebones. ## Frequently Bought Together - JOR Water Conditioner Calcium Rocks for Baby Shrimps, Isopods, and Crayfish, Enhances Pet Color, Provides Hideout, Breeding Spot, Beneficial for Shedding, Rustic Decor for Big and Nano Tanks, 3.5 oz. - Aqueon Omnivore Shrimp Disc Food 1.65 Ounces - SunGrow Cholla Wood, 5” Climbing Logs, Chew Toy, Aquarium Fish, Snail, and Shrimp Driftwood, Tropical Freshwater Fish Décor, Adds Raw Beauty, 3 Pack --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/481774368-jor-water-conditioner-calcium-rocks-for-baby-shrimps-isopods-crayfish](https://www.desertcart.hr/products/481774368-jor-water-conditioner-calcium-rocks-for-baby-shrimps-isopods-crayfish) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-08-08*
