Flatworms... again

[aromantis]

I have a huge plague of flatworms, and want to get rid of them ASAP. I've read that I should reduce feeding, but I only have a mantis shrimp that I feed maybe once a week at most. I also have good flow, so I don't think that's the issue.

Anyway, I'm just wondering what I could do besides use FWE (much too many... I'm certain they're death would poison my 20 gal), and water changes (been there, done that). I've heard that peppermint shrimp might help, and would also serve as food. They're cheap, so I figure I could buy a few, and they could help lower the population and then be eaten. I just don't know how effective they are, as I already tried an arrow crab which didn't work. THX in advance.

I have heard some wrasses will eat them. I was plagued in my 14 biocube for about a year. Kept using FWE but they'd always come back. I borrowed a pinstripe wrasse for a couple months then gave it back. It's been months, never seen another one.

The problem is that anything I put in there will get eaten, and wrasse are not cheap.

Siphon them out either during water changes or hook a media bag up to the end of some airline tubing so the flatworms get caught but you can reuse the water, do that a couple times and get all you can see than FWE. That's what I did in my Aquapod twice, there were a decent amount and the first time didn't get them all. Also add a couple powerheads in there, they hate flow and that will get rid of some and get the rest to congregate in lower flow spots.
