Is This Normal

[dude the 4th]

In my 100 liter tank i have beunos aires tertas, every now and then they will pull a snail off the tank walls bash it out its shell and eat it. I feed them plenty so i dont know why they do this, is it normal?

If they are pest snails, they are doing you a favor! I can't see anything wrong with it otherwise
