Aquarium Advice Regular
Hi, so at night when the lights go off and the moonlights are running there are these tiny worms, probably no less than an 1/2 inch in size, that rise to the top of the surface where the moonlights are most direct. The reach the surface, curl up and fall back down to the substrate and then repeat the whole process. Many are sucked into the overflow, but there must be several dozen of these worms at any given time. Any thoughts?
