I'm reorganizing my Leichardti Arowana tank and getting him some new tank mates.... most likely a bunch of Bichirs, Dats and Loaches. I currently have a natural tone gravel in the tank and considering swapping it for sand.... or possibly even a bare bottom tank for ease of maintenance..... I know it a personal preference but what do you guys have? Bare bottom or Sand..... 
**I know there's probably already a thread about it but I'm scooping out gravel right now and don't have the time to browse the forum just yet.... sorry**
