My apple snails loved this! they were instantly attracted to product! devoured the whole within 24 hours. The size and the cute design was fitting for a fish tank. I'm hoping this helps with my snails shell brittleness.

The unintended Mystery snail nursery I am running couldn't chug along without these excellent calcium feeders. All my snails and shrimp love to eat these. I love this brand of aquarium foods.

Great and convenient. My snails and crayfish love it. Much more convenient and less cloudy than loading egg shells. The critters love to chow down on them, and they have noticeably improved the shells of some of the weaker animals.

This is a fantastic product! My shrimp and snails absolutely love these calcium feeder shells, and they’ve been doing great since I added them to the tank. The shells are thick and high quality. I’ve noticed improved shell condition and activity in my snails. Very happy with this purchase — will definitely buy again!

I have adopted 2 turtles, red slider and something else? Big Bertha is very large, 11"" span and little buddy is about 6" . span. They were left abandoned in a rental house. They were not in the best shape but not too bad I read up they needed calcium. So I was hesitant to try these shell shaped tablets. They came in 3 sizes. I didn't know what size to get so multiple sized would give me a chance to find out. I first tried cuttlebones like birds use but that was a major failure with both turtles. These hit the spot both turtles love them. These are like xsm/small, sm/small and medium/lg sized shells. They eat them like candy. They are hard and can chop them up easily. no waste. I have since re-ordered in a larger quantity since I know they love them. Give them a try, your turtle needs calcium.

I ordered these as a calcium supplement for our mystery snails, intrigued that they offered more nutrition, and was pleasantly surprised to see them arrive with a nice sample of this company’s other products; specifically their 12 type pellet mix and 4 type wafer mix. We put the calcium feeder in the tank and one of our mystery snails literally made a beeline for it and parked himself on top of it for a good 5 minutes, as our corys also swarmed and tried to take a nibble as the snail actually flicked them away. Then we dropped some of the pellets and wafers in and all the fish went nuts for it immediately. The same mystery snail then hopped off (as another arrived to hop on) the calcium feeder, grabbed one of the wafers and curled himself up snacking on it as he held it. I attached a photo. We’ve never seen behavior like this for food before so I wanted to leave a review right away. That particular snail is normally lazy as can be. It was really amazing to watch. Great product, we look forward to reordering and checking out more of this company’s products! Always nice to support a family run business that clearly cares about healthy fish keeping!
