I have like a fungus type deal not on my fish but if like i don't clean my glass off it eventually builds up there. it's also on my swords growing off the leaves. it looks like little flowers. theres like a little strand where it starts then if you look close at the end theres little wavy things. and theres hundreds of them just waving around with the currents in my tank. so i clean the glass and rub my fingers on the plants to get it off but eventually it comes back. does anyone have experience with this? how can I get rid of it?
