what do they do?
what they do is the minerals in the leaf can help bettas from having diseases, and also helps them breed better than justusing a regular styrofoam cup. it is also a base for the male betta to blow his bubble nest
and does anyone here have any?
yes i have 3 left but i am using one of them which means i have 2 extra and 1 using
how do u use them?
its really easy, all you do is just place them in the water and soak it for a bit and let it float while later on the male will build his bubble nest.
