dangit i have FLATWORMS

[nagreen]

I have flatworms. This is a Red Sea Reefer Nano. They're currently covering one rock in my tank. Completely covering it and have made their way onto a mushroom I have and the shroom was shriveled up - which is how I found them.. The rock they're on has been live rock for at least a year, maybe two years - the rocks that they aren't covering was dry rock and has only been in the tank for a couple of months now. I assume they're only on the one rock because it has the algae/food that they're after. which could be a good thing, keeping them contained.

I know most of my options and would like to try the natural route. I don't want to get into chemicals if I don't have to (Saliferts Flatworm Exit).
Here's my issue, the best option I've seen is to introduce a wrasse to the tank. This is only an 18" cube so not sure if a Melanurus wrasse or Coris wrasse would be fit for a tank this size. I don't want a six line due to aggression issues. The same goes for damsels, which i've heard will eat flatworms.
Should I just get a juvenile melanurus/coris wrasse and rehome it when it outgrows the tank?
Or try a "less aggressive" damsel?
Or possibly a couple nudibranch? I just assume these would die once the flatworms are gone.

Recommendations?

I have the 625XXL and had an issue in the beginning w flatworms( got some chaeto that they came in on) and my melanarus wiped them out. I’m not sure how feasible it would be putting one in a tank that size but if it’s possible I would do it and then rehome the fish

I had a 6 line and he barely made a dent in them. I'm going there chemical route.

Anyone know if Possum wrasse eat flatworms? Those seem to be small enough and would get along with tankmates

Do Springeri damsels. They aren’t aggressive and should knock down the population. Additionally, they look really good.

Would one be enough or would I have to add a few?


Another option I'm seeing is a scarlett pinstripe wrasse

I'm leaning against the damsels..

leaning towards
1. small melanurus wrasse
2. small coris wrasse (will it have aggression toward my midas blenny because of color issues?)
3. scarlet pin stripe wrasse
4. possum wrasse

those aren't necessarily in any order.
I would love confirmation on if the scarlet pin stripe or the possum will eat the flatworms...

I’ve never had damsels eat flatworms. My favored finned flatworm destroyer is the dusky wrasse, though they can be tough to find and get large (mine is 7”). I’d be inclined to go hoevens and rehome when it gets too large.

I have used Flatworm Exit several times with no issues at all. Corals, fish, shrimp, crabs, snails, pods all fine and totally unaffected. Be sure to remove as many flatworms as possible before treating, be ready to run fresh carbon and do a good size water change. I normally need to do a double dose before I see flatworms dieing, regular dose just irritates them.

I have loads of flatworms and a possum wrasse. I consider the worms free inverts and they can stay as long as they like. I also know they will disappear soon as they always do
