I have apple snails in a tank with my red cherries. I like to drop in a calcium pill which is just plain calcium with no vitamin D. It helps the snails have stronger shells. Just wondering if it would harm my shrimp at all?
I don't know, I got them from a seller on AB but really according to what I've read, any calcium tab vitamins you get should be fine, the ones I use are oyster shell calcium tabs. Half a tab for 10 gallon once every two weeks is what I generally do.
