I am slowly ramping up my reef tank, but these flatworms have built up a solid population. I am assuming these are the harmless brown flatworms. The only coral in the tank for the last 5 months is a ricordea shroom. Any idea what type of flatworm this is? FYI, I have a melanarus wrasse in QT - I'll introduce these to the QT tank for the wrasse to learn.
