I just found this worm crawling around the front glass of my large split tank. Its about 3 inches long and so weird! Its pink, translucent, and yuck! Where could it have come from? I have had this tank for a long while and have never seen one worm. Nothing new has been planted or introduced into the tank. It inches along like an inch worm. I hope its not a parasite of some kind. Ew!
