This is normal for most fish.I used to have black mollies that did a similiar thing to my plants and completely wrecked them.What type of plants do you have beacuse if you have something like cabomba(is that spelled right)I suggest getting sturdier or artificial plants
What type of fish do you have beacuse most fish like plants.If you can't get any alternatives try feeding your fish lettuce as it will persuade your fish to leave the palnts alone
