That is a good question , but I ve seen many forum members post pics of plants that were semi aquatic . Just a guess but was it from a large chain store?
Besides reading info on here, the best thing you can do is find a good local fish store & figure out which employee knows there stuff & use them exclusively for helping you. I prob went to half a dozen before finding a good one, it s an hour drive but I won t go anywhere else. I walked in with a lonnnnggg list of questions & said, ok- who has the patience for a beginner. PM me if you want some key questions to ask. Also, do you have a liquid test kit?
