okay a couple of weeks ago i lost all of my fish to Camallanus Worms except for 4 baby guppies. i moved them to a clean tank. well tonight i noticed another Camallanus Worm hanging out of one of my female guppies anus. Then i saw one on a peice of gravel. So i ran to get the meds I ordered to use on my sick guppies, but never got a chance to because they all died. So anyways, I put in some of the meds and all of a sudden I start seeing a ton of White worms wiggling around in the tank. it looked like they were dying. they would wiggle then just move with the water, then wiggle some more. Where they heck did they come from? I'm going to check to see if the Camallanus Worm falls out of the female in the morning, if it does, i'm sure i have killed them all i guess. Should i do a 25% or 50% water change in the morning and add more meds??? Any help would be great. these are small teenage guppies and the last I have, I want to save them
