Flatworm ID

Just noticed these guys in my coral quarantine tank. I think they're polyclads but want a second opinion

BTW they are about 1/16 of an inch long

aecola flatworm. Siphon as many as you can with a 3/8" tube. If a large amount, consider adding a wrasse that will eat them such as :
6 line
yellow coris
lunare
melanurus (gets large)

Not harmful as red planaria but can smother base of coral blocking light for its food production

Thanks, These are in a 15 gallon water Box that I have set up for "nuisance" corals that's also used to quarantine other corals before they go into my DT. I don't have any fish in there or plan to put it in so I probably just use flatworm exit.

Dose exit at 80^ of recommended and siphon bottom daily to remove dead ones which can release toxins
