I was looking at my tank last night and I noticed tiny white worm looking things crawling around on the inside glass of my tank !! What are they? Are they harmful to my fish?How can I get rid of them? Any help would greatly be appreciated. Thanks.
those are just glass worms their beneficial to aquariums so you dont need to worry but if they bother you that mutch you can eventualy get them out by frequent water changes.
I had them a couple of weeks ago, due to overfeeding to make sure that some new fish were getting their fair share of food. The outbreak was like instantaneous, haha. I ended up doing some water changes, put some small chinese algae eaters and dwarf gouramis in my sump and that did the trick.
