A non reef safe Molly?

[renegade]

Hi,

So I have a couple of Mollies that I gradually accumulated to Saltwater and have been in the tank for a few weeks now. A few days ago I noticed an odd behavior from one of the Mollies, it was nipping (eating) the "polyps" of my Toadstool coral !!!

See the video...

This was unexpected as I was worried that the dumb Mollies would be eaten by one my corals instead...

Can anybody provide an insight into this behavior?

They peck at everything but they never actually damage coral once they realize what it is they let it go. They don't have teeth to rip flesh with

Why would it do that? It is only picking on that coral, and the other Molly never does...
