These showed up in my fugee about 6 months ago when i added some hand me down cheato. the population grew fairly quickly untill my bworms picked up in size and now the fws have died back... Never seen any outside of my fugee so..My oppinion would be to let the bio system sort it out : )

I have planaria myself, not too concerned, I do weekly water changes, and dose FE 30 minutes prior to changes. I have notices there are a few still around, but made a dent in the population, I will just continue the regiment until the life cycle is broken. They are harmless unless you see them on coral plugs or around the corals, they can irritate corals if the population gets too out of control

Did you have any mini brittles when you dosed? I had them in two tanks that I dosed with FWE, and all the mini brittles came out of the rocks and formed a massive writhing ball of death. Just curious if that was the FWE or the toxins' those red ******** release when they die. I don't blame FWE at all - they got rid of my issue with tactical treatments. I miss the mini brittles though .

No I didn't. I removed some 6 rather large bristle worms so far, wasn't planning on thinning their population. But they were removing food from the hermit crabs and causing the crabs to always pounce on my snails or smaller hermits.
