    Flatworm ID?

    I found this little creature crawling on my glass at night, and I believe they’re flatworms. Can anyone help ID this? Or at least tell if they’re harmful or not? It looks transparent/white with black dots on them. Doesn’t look like brown flatworm unless it’s a baby.

    This is my first tank and I have been keeping it for almost 1.5 years. I have no idea what these small black polyps are that are growing like crazy. They seem to be a small fast-growing coral that closes when I touch it. My LFS told me to basically perform surgery and get the zoas off that...
