I'm really puzzled because I have very low nitrates and no detritus in my tank.
However I just noticed this guy crawling on the back glass. He looks like hes like 1.5 inches, which I've never seen that big of a detritus worm before.
Looks more like a type of roundworm. Don’t look like detritus worm. Would remove and recheck all ur decor/plants etc. Clean out any area of debris. Fish acting normal? If good then watch for now. If more come back or see another then consider using levamisole or febendazole.
I just removed almost all decor in the tank last night but didnt see anything trapping a lot of dirt.
I am in the process of getting rid of my FX6- I'm wondering if this could be the issue as I only clean it as soon as I see a reduction in flow or higher nitrates. (Hate the maint on that thing! Lol - going back to HOB)
Before reaching out for any meds (fish are looking/acting normal so far) is there anything around the house I can use to kill these things or make it less hospitable in there?
