    • Great product. Saved my snails.
This is 100% worth every penny. I struggled with my snails adding supplements from my local fish store and even cuttlebone and my snails were still having issues and not eating it. Since trying this, my older snails are doing better and the younger ones are looking so good as they grow. They even reproduced. My corys and plecos love it too! ... show more

    • Repeat order
I got these for my great nephew's shrimp tank. They're a great quality product that's nutritious, won't alter your water chemistry, and all the aquarium critters (shrimp, snails, fish, lobster) LOVE these. Them being in a small flake format makes feeding so easy, too. Also, these are a ZERO waste product! ... show more

Great snail treat. Different flavors, they sink well and are a great size. They haven't clouded the water. Convenient easy store packaging. It is just a nice product I would recommend. You can see a white piece inside the aquarium for scale. The snail is to the left and my betta to the right is checking it out also in one photo. ... show more

    • So much better than shrimp lollies
These things are great. Actual nutrition that shrimp and snails need. One small piece goes a long way and if I haven't given my critters one in a few days they go nuts over it when it gets dropped in. I have a caridina shrimp tank with 0-1 KH so calcium supplements like this are essential.

    • Great nutrition
My snail and shrimp love these! The minute I drop them in the shrimp come right over! Ive also handed one to our snail and he sits and eats it. They do get white crumbles all over but easy to clean up. I did notice our snails shell get stronger after 3 weeks of using these

My snail loves these, and his shell is sooo much stronger and healthier. I purchased these 7 months ago and in the picture, you can see where his old growth was when I purchased him at the pet store, and his new growth that looks amazing!! Would highly recommend these for snails.

I've bought this now for about a year, specifically for my neocardinia shrimp. Since using it, I've seen so much better molts!! Hardly any molt deaths! Plus it helps my pink and blue ramshorn shells look absolutely so pretty and strong. I can't recommend this enough! I put about 6-8 in my 40g with a few hundred shrimp and snails, about once a week. So they really do last. I have black sand so for a little bit of time until it's eaten it does kind of break apart and look a little chalky on the sand, but it goes away. I don't know if my shrimp prefer any of the colors or not but they sure do come out of the woodwork to eat it! The price that it is it's worth buying if you keep shrimp even as a hobby just to prevent them from having bad molts. Great stuff! ... show more

    • Good deal
My snail, fishes, and shrimps all love it. When I drop it they all rush to it. The only problem is that my betta gets over feed from this. But nothing i can do. He fast, and snail and shrimps can be slow. Good quality, and help varied their diet. Just drop 1 or 2 in there depending on the population. ... show more
