I have a planted shrimp tank with top soil covered with black flourite as the substrate. Little mounds of dirt started appearing that had a hole in the middle (like a mini volcano). I started to notice that worms appear to be the reason. I need help identifying them and im looking for suggestions to get rid of them. Picture to follow shortly.
They are reddish/clearish and will swirl around when they come out of their hole.
I have a few tubifex worms in my 20g planted, I've had them on other tanks as well.
I think they're great. Free fish food, shrimp may eat them. They won't tear up the substrate, but they will aerate it. I love the little guys. Plus, they feed on detritus / siphon the water. They're good guys.
