Flat worm question
 

I seem to have picked up some flatworms, likely with some new rock I added. They are starting to appear on the glass and substrate. How can I limit their spread or, better yet, eliminate them without removing bits from the tank? I did a fresh water dip with the new rock but they must be hardy little buggers. :evil:

TIA.

Never tried it myself, but you might try this.

Flatworm Exit

There are some wrasses known to eat flatworms as well, leopard and six line. There is also a flatworm eating nudibranc but that will starve and die once the flatworms are eliminated.

Cheers
