I got a lot of different colored sponges growing around my tank, including amongst some zoas. I haven't bothered them, nor have the sponges bothered anything that I noticed.
Sponges are reported to filter absurd amounts of water for their size, so I see them as a benefit to my tank.

If they are under the rock then just let it be. But if they are beside your zoas i would keep an eye on them. Some will grow over the zoas mats. And if it's beside your zoas they will stop your zoas growth as the zoas won't grow over them. I usually just take a toothbrush and brush off sponges. I wouldn't do this in the tank as some sponges release toxins.
