Red planaria eating fish

[Subtropic Reefer]

I have a big red planaria flatworm problem but do not want to use chemicals. I have no fish and it is a 25 gallon tank. What are some good fish I can add that will help. I’m thinking a six line and a scooter blenny?

I had red flatworms (and still do in my sump) but either my spotted mandarin or my melanurus wrasse eats the ones in the display tank. I'm not sure which since they were added around the same time, with your size tank a melanurus isn't an option but a mandarin may be okay in your tank.
As with any fish it comes down to the individual fish as to whether they will eat a certain pest or not.

I tried 4 mandarins and scooter Blennies with no success. Maybe you could try pipe fish. Or six line wrasse but it's a small tank even for a six line.

At your tank size, research the Springeri Damsel. An excellent tank mate in my 40

I’m not aware of any fish which will eat these consistently, however I’ve had great success with blue velvet nudibranchs.
