Hey all... I have a 180 gallon African tank with some mbuna, haps and peacocks; it's pretty well stocked and healthy. Today I saw a little stringy, wormy thing swimming in the water! It was about an inch long, white or tan, and not much thicker than a hair, but it was swimming through the water like a mini-snake! I tried to net it, but then lost it b/c it was so small, and then I saw a smaller one that was about a 1/2 inch... Any thoughts?
