Ok I have figured out how to keep fish through the winter but I know nothing about plants. Hoping some of you can tell me which plants I can cut down and plunk into 2.5 feet deep water and what needs to come out? Any other advice? FYI I took the lily pad out, cut it in half, and put it half into my 40 gallon tank and half into my 75. The tall stuff, cattails maybe, looks terrible right now. I think a couple of them are corkscrew rush? Then I wonder about the big purple one and the one under it, submersed in water. Thanks so much!
