I don't know where all this info is coming from, I might have over fed my shrimp when I got them but I have since removed their gravel and stopped feeding them almost altogether (they eat off the glass and live plants) and I also suction out the planaria when I see them. They still multiply. So I am one of the minority whose planaria thrive without the tank being overfed lol
I actually saw a bigger one aside from the tiny ones that I see and I think they're detritus worms, all the pictures I looked up of planaria the things seem to have arrowheads. The big one that I saw was really long and thin. Trying to find out more, it seems like you can't really use any chemicals as they're either dangerous for the shrimp or the snail. I just did a water change and vacuum of the gravel yesterday.
