I moved my small bichir from a 10 gallon to a 55 and turned the filter off in the 10 because I never intended to use it again, for a few months I had noticed white little things that almost looked like microscopic pitchforks attatched to the glass, so last night befor going to bed I checked the tank and the glass was crawling with worms about half a cm long and as thin as a hair , I poured alot of nox -ich in so nothing would survive , is that ich? and why did the worms things only appear when I turned the filter off?
