Review: Noticeably healthier snail shells - 55g planted. My Malaysian trumpet snail army and Nerite snails approve. The MTS are noticeable larger than before. The Nerites no longer suffer from shell erosion. The shrimp and fish love to eat them too, although this wasn’t bought with them in mind. I suppose the egg-carrying female Amanos look a bit bigger and robust than before. This has been a very beneficial supplement for the tank and a little goes a long way.
Review: Shrimp love, but can be messy to get out if over fed - had it for a while and can confidently say my shrimp love it. they fight over it all the time. it may look small but there is plenty pieces inside and they're pretty easy to chop in half if you need or want smaller pieces. i will say it is hard to get out if youve put too much in, it will crumble apart into many tiny pieces so be mindful about how much you put in so you dont have to deal with the headache of getting it out. i alternate from shrimp pellets and these for feeding days in my shrimp tank and they are doing great.

### ⭐⭐⭐⭐⭐ Fabulous!! My snails love it!!
*by C***U on March 3, 2026*

First off let me say that I really enjoy my aquatic snails and try to give them the very best. I found this supplement when researching new(er) calcium products on the market. They were not crazy about the previous calcium supplement I used and it mostly just dissolved into the water column. But they LOVE this! They eat it just like their regular sinking food. No piece of this has ever remained overnight so they’re definitely drawn to it. My snails have grown rapidly, are regularly active, and have bright colored smooth shells. I do believe this supplement has contributed to them thriving. I will buy it again. As well as try other products from this company.
