I got a sword plant the other day. it was 1.99 at pet supermarket...It didn't say exactly what type of sword it was it just said sword plant.. I am curious though..Do sword plants need co2? I normally will give my plants a little bit of fertilizer and proper light and they are ok. I don't use c02 in my tank.I mostly have anubias, java moss and wisteria though. Do you think the sword plant will survive under these conditions? I am interested in buying a few more but I am using this one as a practice sword for now.
