with this tank i am focusing on my geo red heads and thus its not densely planted at all, lots of open sand for them to sift. as substrate i am just using pool filter sand and the only other plants are all anubias, ferns, and some moss. i'm not fertalizing really at all right now. i would like at have some plants floating up top to help filter the light a bit and make it feel more natural for them what not. i have worked hard to rid myself of duckweed in this tank because its too messy so i'm not into that. any suggestions for plants that are either floating or look pretty good floating that dont get too messy (ex. drop leaves easily) that i might not have thought of?
