Hey guys, I hope someone can help me here. I have a 40 breeder planted that I started cycling 2 weeks ago. About a week in I have these red worms popping up only on my hard scape at first and now they're crawling around everywhere. I can't identify them and I don't want to start populating my tank until I know if they're harmful to the fish and inverts. They seem to have a "hand" on their back end that they use to grip the rocks, are bright red like bloodworms(that's what I thought they were at first) and segmented. I've had tanks most of my life and serviced them professionally for multiple years. I've shown pictures to multiple fish stores in my area and no one has seen these little guys before. So I'm really hoping someone here can help me.
