i bought a couple of vallis plants about a week ago from my lfs, they started to look like something was nibbling on them and a few bits were coming off and floating to the top, but the i spotted something moving inside one of the leaves it's like a small catterpiller about 1cm long i've since found a couple of others so i've binned the plants, any idea what they could be i tried taking a picture but they don't come out very clear.
should i be sterilising the plants first and if so what should i use.
