Ornate for sure. He will get 20-24 inches long so make sure you have the room for him. Any fish that can fit in its mouth will be eaten lol so watch out for that. Also, polypterus have a crude lung that allows them to breath surface air, so you will need a tight fitting top to your aquarium because they are notorious for jumping when getting air. Oh, and be prepared to buy more bichirs, because after one, you cant stop.
That I'm sure of.... they're an addiction.
I remember when I got my first Bichir I was like "Oh I've seen lot's of MFK members with Bichirs, I'll try one" and now the only fish I buy are either Bichirs or feeder fish for my Bichirs
