I have a Montipora (no idea name or type) that I received for free a month back. It was tiny, and it started to grow nicely but I have noticed a weird green/white spot in the back (circled in red) along with a new one at the tip. Details on the tank below, but curious what may be the cause here. Another monti (encrusting, fruity pebbles) is growing beautifully, so I am at a loss to what is going on. My other SPS (acros and other types) are doing just fine.
