I'd like to have my class look at and try to identify some of the critters thriving in the substrate of our class tank. Unfortunately, I haven't been able to find any internet resources to use. Does anyone know of any? The organism that seems to be the most abundant is a red, semitransparent worm that magnifies to about an 1/2" under 25X magnification using the stereoscope.
