Matt I suspect that it was not a black worm, but a leech. These are sometimes found with black worms. It also seems the larger the black worms the more leeches you find. I would get the fish out of the tank as soon as you can. The leech might leave the host and remain in the tank to live of other tank mates. I would disect the fish to be sure the leach is not in the tank (that is if its dead now). Its not that hard after all your not doing a science project. If its still alive look behind the gills. Sometimes you will be able to see it there. If the leech is there you can remove it with care making sure you remove its head. mudpuddle@ccis.com - ---------- > From: Matthew Diller <mdiller@MAIL.LAWNET.FORDHAM.EDU> > To: apisto@majordomo.pobox.com > Subject: Re: Death by black worm > Date: Monday, March 09, 1998 2:32 PM > > > This morning I was feeding some delectable black worms to my large healthy male a. cauc. when he suddenly freaked out and went rigid.

Can a black worm (I guess a relative of tubifex) really kill a fish? > > Matt Diller > > > > ------------------------------------------------------------------------- > Search http://altavista.digital.com for "Apistogramma Mailing List Archives"!
