For an Ornate bichir you will need a large tank fine subtrate, planted and places for him to hide.
You must keep the water level lower than usual and have an airtight lid. Bichirs come to the surface for air and if not happy in their home will find any hole available for escape. They are great fish I have one myself. Mine loves to eat frozen krill. They will eat any other fish they can fit into their mouths so be careful what you choose to house with it if anything.
