Definetly a briste worm. You have more then you think in your tank. Next time you feed your fish, take a closer look at the food that sticks to the substrate and rock. Chances are you'll see some of these scavenging for food. Or after your lights have been out for a few hours get a flashlight with a red filter on it(crtitters wont see that spectrum) and you'll be surprised on what you'll see. |
