Can you get a better shot? Hubby says they look like sharpie squiggles because the thread pattern comes through the black color? Could you get one and put it in a white container to get a better pic? Thanks.
Its called..flat worm or round worms. Can't remember the exact name, but you should get rid of them. If I remember correctly, I had it one time because I was over feeding. It's been such a long time that I can't even remember the name. Do they have like a flat head?
Ok. Even though we’re not exactly sure which larvae they are the consensus is to get rid of them. Before the become adults and turn your filter into a nightmare. Hey! @Goldiemom do these look like your bloodworm problem or a different fly larvae?
Thank you all so much for your help. I decided to wage war against them, because if I am not 100% sure I didn't want to risk it with over 70 fry in my tank. The deed of getting rid of them (or at least the ones I can see) is done.
