I.D this aquarium Parasite help please?

  This worm is bright red, has a forked tail and a caterpillar like head.It came out of a fish when we purged for calamanis worm with meds.There were calamanis but this worm is distinctly different.Where the meds killed the Calamanis, this worm was only stunned and when in container appeared too eat the calamis worms.



Here is a picture of the worm in container with the calamanis: http://i265.photobucket.com/albums/ii221/aussie123_2008/IMG_4294.jpg



We are finding it very difficult too ID this worm on the internet, I am hoping you guys will know as these worms are continuing too come out of the fish when we re medicate and is of concern too us as the fish is of extreme sentimental and financial value too us.I am sorry the picture is not bigger, the worms are only small
Looks like fish leeches based on pix vs pix comparison.
