Flatworm eaters for a 15g Nano

[sammy33]

I seem to plagued with Flatworms in my tank. The problem has gotten better and the flatworm population has decreased after treating the tank with Greenex and adjusting my feeding schedule. I have but one fish in the tank being a Yellow Watchman Goby.

So I am thinking of adding a Six Line Wrasse. I have heard that they will munch on the Flatworms.

Any thoughts on other natural Flatworm exterminators? Nudibranchs?

I have heard that blue velvet nudi. will eat flat worms

Six Lines are hit or miss on flatworms.

pardon hijacking the thread but...when I initially started my tank I saw a couple of flat worms on the glass but after about 4 months now I have not seen one and although I figure they are still there, it certainly has not turned into a population explosion so, in general is my tank going to continue to get along without a flat worm explosion or will the uprising occur in a few more months?

Flatworms are a bit of a problem in the sense that they can eat coral polyps. They are a reall nuisance in a Nano because when they die off they can release a lot of toxins in tank. In a small Nano Reef this can be problematic with the water volume not being able to handle the sudden increase in toxins.

I am reluctant to use anything like Flatworm Exit or other anti-protozoan treatments because of this. In a larger tank it is not as much of an issue because the tank volume can absorb the chemistry cahnge much better than a Nano.

I think that Natural Predation is good option. Maybe a Canary Wrasse? Although I already have one Yellow fish?
