The snails seem to enjoy them, and occasionally my shrimp and fish nibble at them too. I haven't had any issues with my snails' shells, and I'd like to think that this is contributing to their shell health. This doesn't seem to affect water quality and is a pretty large supply for the 2 snails I have, so I imagine it will last a long time. Review: Premium product at an excellent price - The shrimp and snails love these calcium squares I drop them down the feeding tube and it ends up turning into a tank frenzy haven't had any issues with failed molts my snails have beautiful shells no cracks no erosion and they're breathing always a good sign but my opinion it's a great product it does not cloud the water whatsoever once they dissolve that's it and the good thing is you just put calcium in your water because your plants actually need calcium as well so factoring that in they got a customer for life with me I pretty much bought all of their products on that line and they're all great ## Features - What animals eat them? neocaridina/caridina shrimp all aquatic snails (mystery/ramshorn/rabbit/all!) plecos any fish that loves to steal bottom feeder food!

The moment I dropped one in, my loaches, platies, and shrimp went absolutely wild for it. I’ve never seen them respond so fast to a food before. In my glass bellied guppy and shrimp tank, an Amano shrimp literally grabbed the bite and walked away with it like a prize, which was both hilarious and reassuring. While these are clearly designed to support shrimp and snails with calcium and protein, it’s obvious that the ingredients are very appealing to other tank inhabitants as well. Everything went after it immediately. I’m mainly using these as a supplement, not because my shrimp or snails are struggling, but to give them some extra nutritional benefits and support healthy growth and molting. Based on how well it was received, I feel confident it’s doing exactly what it’s meant to do. Overall, I’m extremely impressed and will definitely continue using these a few times a week. Watching the feeding frenzy alone makes it worth it. ## Frequently Bought Together - KatsAquatics Calcium + Protein Tablets - Great for Picky Eaters - Snails, Shrimp, Bottom Dwelling Fish, Plecos, Crabs, and More! - KatsAquatics 3-in-1 Limited Edition Calcium Tablets for Shrimp/Snails (Nutrition+Immunity+Protein) 1.7 oz - Invert Aquatics Micro Mix - Sinking Blended Diet for Snails, Shrimp & Bottom Feeding Fish (1.5 oz (42.5g)) --- ## 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.de/products/426825122-calcium-protein-for-strong-shells-healthy-molts-100-natural-does](https://www.desertcart.de/products/426825122-calcium-protein-for-strong-shells-healthy-molts-100-natural-does) --- *Product available on Desertcart Germany* *Store origin: DE* *Last updated: 2026-10-16*
