Hello
I have a unknown organism in my tank and I don’t know if it’s good or bad and I have had it now for about 6 months or more that I know of. Some will say it’s flat worms but I don’t believe it is, to me it looks like some sort of mollusk larvae. They attach on the edge of the hard disk to rock surfaces and the flap back and forth in the current and never move. They are thin hard disk with an opaque dot on one Edge closest to where it’s attached.
