  • Easy way to ensure your shrimp get all the calcium they need! Great product!
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

  • The shrimp love them!
We've tried a variety of foods with our little shrimp. Dropped a few of these into the tank once the package arrived and they just wow! They were ALL out and eating! Even spotted a few tiny baby shrimp we didn't know we had!

  • Buy it your 🐌🐌 will thank you
This stuff is fantastic. No joke my snails absolutely love this food and I am so happy that I found it please keep it around because literally as soon as I put it in there they go right to it my two smallest snails like to pick them up and slide them up the glass and eat them like toast it's so funny but anyways I would definitely suggest this for any mystery snail owners it works like a charm and your babies will start growing like weeds my Gary is so big his foot is so big and his shell is so healthy now I'm so happy my Sandy cheeks is my female and she is getting so much healthier as well Cosmo and Wanda are my two newest ones and they love it as well so I'm happy happy thank you so much and keep it coming just ordered my second bottle... ... show more

  • Community tanks love these!!!!
Mystery snails love it! Actually my whole tank loves it. From my loaches to my platys, and of course my pleco. I found if i press a small piece against the glass directly in front of my snails path, the snail actually get to eat it vs I've had literally every other fish in my tank flip the snails over to get to the food. Pic included to show ya what I mean! ... show more

  • Snails are healthier now and it doesn’t cloud the water.
My local petsmart person told me about this product for my mystery snails. it brought them back to good health and strong shells and didn’t cloud the water. I’m happy. And so are the snails. A little pricey but worth it.

  • Not their first choice
My shrimp will eat this but it’s not their favorite. Even though I give them small amounts there’s always some left over. Looks like they prefer algae and this is their second choice
