Inception 0 Posted July 19, 2013 Hi everyone, it's Inception. Anyway two days ago I found these worm shaped things on the sides of my tank and I freaked out and moved my goldfish from the plastic tank it was in to a different (food safe) container. I don't know exactly what they are but it can't be Planaria because they aren't moving let alone swimming. Will these things hurt my fish or was there no reason to move my goldfish, Posen? Here's a picture. I just realized I am probably infamous for this tiny little plastic bin my fish has been living in while my 40 gal is cycling... 0 Quote Share this post Link to post Share on other sites
shakaho 6,312 Posted July 19, 2013 It looks like debris stuck to the side of your tank. Wash it off. 0 Quote Share this post Link to post Share on other sites
tithra 4,917 Posted July 19, 2013 It is difficult to tell exactly what it is from the pictures, however if they are worms it is highly unlikely to be anything harmful to your fish. Parasitic worms as a rule live on/in the fish. Worms found in the tank are typically not harmful. I would take any video or other pics you might want to of them, then clean out the tub well and move your fish back in 0 Quote Share this post Link to post Share on other sites
nicoleauryn 46 Posted July 21, 2013 Probably some sort of midge fly larvae, I have had them in my tank too. Mostly in one of the filters once. 0 Quote Share this post Link to post Share on other sites
GoldenSpoiledRotten 6,786 Posted July 21, 2013 I agree with Shakaho. It looks like small Poops on the side of the tank. I'd give the whole thing a scrub. 0 Quote Share this post Link to post Share on other sites
ichthius 122 Posted July 21, 2013 (edited) Siphon a few into a net and rub them between you finger to get the case off. Look like bloodworms. Midge fly. Just posted a video last night of the bloodworms that grow in with my ranchu. Not imbedded yet, to busy culling ranchu. http://...................blogspot.com/2013/07/live-bloodworms-co-cultured-with-ranchu.html Edited July 21, 2013 by Ichthius 0 Quote Share this post Link to post Share on other sites
