Best Fish/Invert for Flatworms and Tubeworms in a 15g

[a;lksdjf]

Hello all I have a softie tank that is about 4 months old and I noticed a lot of tiny brown flatworms and white tubeworms on the glass and I'm looking for something that will eat them. I currently have no fish in there and my only inverts I have are a cleaner shrimp, 3 red legged hermits, and a couple of baby rainbow BTAs that are less than the size of my fingernail I'm growing out for my 46g. The only fish I'm thinking of putting in there aside from whatever you people recommend for these worms is my tailspot blenny that's in my 46g, and even that one I'm not 100% on because I've heard that they nip at zoas and palys occasionally. I've heard mixed things about dragonets eating worms, but even with a small refugium and my seemingly endless supply of copeopods and amphipods everybody says it's a cardinal sin to keep a dragonet in anything less than a 30g with a gigantic refugium and sump lol. Go wild with your recommendations, since I'm open to almost anything

Scooter blennies will eat the flat worms in my experience. Several wrasses will as well and some may eat the tube wormed as well.

Leopard wrasses and dragonettes will eat flatworms ime. How big is the tank?

I have a Mandarin and a Ruby red dragonet and neither of them touch the flatworms
