Flatworm I.D. please? (Clear pics provided)

[christianscorals]

Hello. Like many others, I was looking around my tank walls in search for pods. I found many, along with these flatworms. The flatworms seem to mostly hang out in the front glass and i've seen a couple crawling around rocks. Will they eventually start crawling on my corals and messing with them? good guys or bad guys/ neutral? Thanks for any help.

P.S. I have dosed flatworm exit twice within 4-5 months and they seem to be coming back again

i had these! acoel. they decimated my pod population:////

i got a blue velvet nudibranch bc there’s no way in hell i could siphon out every single body with the salifert method (and it doesn’t kill the eggs) (and it’s a race against time and toxicity). the bvn cleared my acoel population within a month (he tripled in size). i run activated carbon to absorb the toxins he secretes and it has worked perfectly. as a juvenile they have no ability to tolerate moderate flow but now that he’s grown he hunts in higher flow areas.

i would like to find some reef keepers that have acoel populations to lend my bvn out to now that i can’t feed him. let me know !
