Most likely Blackworms. They'll be fine in the tank and your fish can eat them if they can catch them.

Hi all, In the same tank that I found that small white worm-like creature last week, I now find some sort of red worm. They are protruding about ¼ to ½ of an inch out from the substrate. They don?t seem to move; just sway back and forth in the current. They are red. They are all over the place and have all arrived in the last 7 days. Any idea what it would be? Thanks Shango _______________________________________________ GSAS-Member mailing list GSAS-Member@thekrib.com http://lists.thekrib.com/mailman/listinfo/gsas-member _______________________________________________ GSAS-Member mailing list GSAS-Member@thekrib.com http://lists.thekrib.com/mailman/listinfo/gsas-member
