I am a Newby
Fish Fanatic
Ok tnx i think i will remove it all and try growing it in bucket or tub and eventualy replacing hornswort with it and ring on top of water.The small floater is duckweed. It will take over your tank. Some people like it, some fish eat it. But if you don't want it, remove every single plant you can find, and keep looking every few days. I speak from experience having just tried to rid both my tanks of this invasive pest plant
I like way hornswort looks planted in subtrate and i have valisneria planted also so dont want hornsworth on top to get tangled with valisneria and planted hornswort as i know i will end up puling them from subtrate by accident if they do.
