Green worms in water lettuce
Hey guys, I bought some water lettuce and began noticing holes appearing in all the leaves. I only have Nerite snails so I assumed this was just some odd melting or something. Someone mentioned again they they looked like they were being eaten. I waited till my lights went out, then went over to investigate and found green worms (looks like inch worms) on all the leaves.
Does anyone know a way to kill them without killing the plants or my fish? I'm thinking that I could sink the plants for a few hours to drown the worms. Will that work?
