In the past I have had red flatworms in my tank but not to the extent that they've been an issue so other than siphoning some out occasionally I never really did much about them. It has been a while since I have seen any in my display but I just noticed that in my (unused) refugium I have a lot of them, but still none that I notice in the display. I'm assuming any that make it to the display are a snack for either the mandarin or the melanurus. Is there any reason to remove them from the refugium?
I can isolate the refugium so I could easily use flatworm exit and then replace all of the water if there is a reason to worry about them.
