I've been struggling with a few of my cichlids having Camallanus worms and grew very frustrated after several attempts at housing them in a quarantine tank and trying a bunch of different meds that I thought did the trick.I put them back into my 200 gal and noticed they still had them hanging out of them.I read that you shouldn't tweeze them out but I thought I'd try it after getting thoroughly pissed off to the point of just euthanizing them to save my other fish.I caught them,brought them in the bathroom and held each fish upside down in the net so I could see the worms and pushed gently on his stomach.The worms slightly protuded out and I tweezed each one out without problems.I really think I got all or most of them and I threw the fish back in their quarantine tank to see what happens.I honestly think it worked very well. Just thought I'd share....
