I've only recently learned how beneficial, instead of devastating most species of bristle worms are, as both cleaners, and as a food source for inhabitants in the tank. I have a single sand sifting star in my tank, and my tank is just about 3 months old, now or close enough.
I also have about 10 narcssius snails & about 15 blue legged hermits.
Would the bristle worm(s) compete too much with the sand sifting star and starve it to death, if I were to get one, or some? I know both are pretty greedy eaters/hunters, as they go through the substrate, and also whatever the snails grab too...
