Thanks for the links and the advice so far! Really appreciate it!
I have just purchased a psychedelic mandarin...would that eat them? (I know its sorta like dependent on individual mandarin but I've only read that green mandarins will eat red planaria...is that true? Do I need to get a sixline wrasse?)
My reef tank setup:
running 8 months
90 Gallon
1 regal blue tang
2 false perculas
1 bicolor dottyback
1 psychedelic mandarin
1 blue spotted jawfish
1 diamond goby
2 cleaner shrimps
hermit crabs and snails, 1 x pompom crab, 1 x emerald crab 1 x tuxedo urchin

It just occured to me I have a refugium and that maybe where the red planaria are coming from? Should I get rid of it?
Thanks everyone!

No dont get rid of your refugium. As cool as 6 line wrasses are most of them turn in to huge wrasseholes as they get older. Bluetang gave you some good suggestions.

HAHA "wrasseholes"
Thanks for the advice all. That Melanurus Wrasse looks amazing...I'm asuming that's gonne become a wrassehole too? Too bad...so pretty!
I'm worried the yellow coris wrasse will not get along with Mr. Bicolor Dottyback...he's a real jerk to all the newcomers into the tank(though he's left the Mandarin alone)

I know my 6 line wrasse can take car of himself against a much bigger tang. Plus hes faster too if he needs to run

Ya they may getted harassed by the dottyback but it pobably wont last long. If you have a fine sand bed it's a good thing for the mentioned wrasses as they can hide out in the sandbed if chased. 6 lines just dont give in until whatever they hate dies, I have a dottyback that usually gives up the chase after a couple of days.

my sixline is the worst in my tank drove 2 black clowns out the tank gave my mandarin quite the harassment but they get along now ,is a peacefull fish untill new fish get added especially fish his size with similar colours

I'd go with the yellow corris, took care of my nudi problem in no time.

My sixline is big. I can't add new fish, but he bothers nothing in my tank.... Not even flatworms.

A spotted mandarin to be specific. They would clean them up in no time.
