I have 2 dalmatian mollies, one im sure is female and cant really tell the other, since purchasing them Sunday they seemed to get along untillnthis morning, I notced the mollie picking on the blue snail......I decided move the snail out from veiw maybe try to hide him in the pineapple figure , but the mollie just went in and hovered over the snail like a guard or bully so to speak, it nips at the blue snail and wont leave it alone, and I currently give the snail algae wafers because the tank has accumulated any algae yet. And the mollie constantly nips at the wafer that the snail is trying to consume, it seems a little harrassing.....what should I do....is this normal behavior should I worry....?????
