Calcium + Protein, for Strong Shells, Healthy Molts, 100% Natural, Does Not Dissolve in Water, Fast Sinking for Aquatic Shrimp, Snails, Plecos and More! Biologist Made in USA

Outstanding product. Stays whole and does not foul the water. Snails and shrimp love it. i also use it in a blackworm culture and have the healthiest worms to feed my pea puffers!

Great. Shrimp love them, snails don’t mind them either. Great way to get calcium, have seen healthier shrimp, with less random deaths in the tank.

Would recommend to anyone with shrimp or snails, since feeding every other day my snails shells have been looking great, same with the shrimp since it helps with healthy molting.

My snails love this stuff!!! I give it to them daily and they are always all over it and it’s gone before the sun goes down. My snails also look more healthy and colorful! This is my go to for calcium.

I've been using this for a while now, and had to come back to say how great it is! I balked at the price, but this little tub will last a looooong time. My shrimps love it, and so do my snails, and even some guppies peck at it. They LOVE it.

Excellent Calcium for abandoned Ramshorn Snails that needed a home. I got snails from store and they were all white shell in unwanted tank. I asked about them and guy said I can have them for free but they need Calcium. It’s been 2 weeks and already their shells are turning dark brown with cute brown spots. Thank you for product! The snails love it.

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.

My snails and shrimp love these. They don't disintegrate in the aquarium. However, the shrimp and snails leave white poops everywhere which is no big deal if you don't have dark pieces of wood decorating your tank.

As advertised. The product was in good condition and I use this for my shrimp tanks regularly
