I noticed this morning several small white worms that are crawling on the side of my large catfish. Kind of a thread looking. Let me know how I should treat would be great and can I treat the whole tank. Fish and plants.
Sorry wasn't around this afternoon. There are a couple that are crawling but I thing there are anchor worms. My tank is pretty clean. Parameters are all good and I vacuum weekly with a 30-40% water change. I don't see any of the worms on the glass.
They aren't hook worms or anchors.... I had this same type of worm on a german ram once and because I couldn't find much detail on them, the ridding of them was close to impossible... let me see if I can find where the post is that found them... ah found it... what they were finally diagnosed as were round worms. I tried using copper safe on him and it seemed to work for a little bit but ultimately, the worms got him..... it was suggested though that I used Levamisole hydrochloride. I heard that it is what gets them and I wish I had the stuff sooner. However, with this being a catfish, you should look into if using this would cause more harm than good on him.
