A new aquarium I am building will have geophagus, plecos, cories and angels. Tank will be 36" tall with LED lighting and pool filter sand substrate. Driftwood and rocks will be primary decorations. What kind of plants could I try? I plan to anchor some java fern and anubias to the driftwood. But given that the geophagus are diggers, is there anything else you would recommend that would do OK in sand? And any methods to keep it buried, etc. Thanks for any input.
