Red Planaria worms...please help

[Tim Plow]

I have recently had these small red square shaped things attaching all over my rock and glass. Before I knew it, they were hundreds of them. I just got done doing a little research and I am pretty sure they are Red Planaria flatworms. I have a 200 gallon reef tank with several nice corals.

What can I do about these worms? Will they kill my corals? Can I manually try to get them out with a net?

Any comments would be greatly appreciated.

Two words... "Flatworm Exit"

Shortly after treatment, you will need to siphon out as many of them as possible and do a water change. I have an acquaintance who lost an SPS using this method, but have otherwise not personally heard of any significant harm done when the instructions are closely followed. It generally takes only one or two treatments to completely eradicate them. After that, be sure to QT or at least give your corals a prophylactic dip before putting them in your tank to ensure you don't get them again.
