invasion of strange plant hitchhikers
Quite a few months back I added some live plants to my 55 gallon tank. I treated them with alum before I added them to the tank to get rid of any nasties. Well, evidently some nasties survived. They look like sesame seeds. They glide slowely along the glass and plants in a snail like manner and have a hard covering that crunches when you squish them. They are the shape and size of a seasame seed. They are kind of a whiteish transparent color with a darker black/brown color towards their centers. Each week I squish as many as possible, and wipe out as many as I can but it is a loosing battle. Each week the glass, plants, and gravel are peppered once again with these little creatures. I think they are feeding on algae. None of my fish will eat them (ottos, pearl gourami, corydoras, rasboras). I haven't been able to ID them. I posted a similar message at a different messageboard but no one there seemed to know what they are. Maybe someone here can help. I'd like to know what they are, and how to get rid of them. I am desparate enough to try chemicals (with my fish in a separate holding tank) if necessary.
