Well that's great.... Any idea how to get rid of them? My tank is an over stocked tank it houses about 30-40 nebula steel guppies (some being large females I read could do the job) and around 50 red rili shrimp which at the time I don't have a population issue but makes me wonder how many babies arent making it and how long before utter doom takes place.
Ever since I purchased some hornwart and threw it in there 6 months ago I've been seeing these things along with pond snails (which I usually dispatch 3 a day still whenever I see them) that's the only plant in my tank....worst purchase ever
