lucky, those are beautiful monsters. I'd love to keep one oneday, but currently the only tank I would be able to keep on in is my friends 20L, which ichtyologist said was fine, but I'd rather get him something like a 30+ or a 55 like you. What are you going to feed him? I'd suggest massivore if you can handle the smell and if he eats pellets, otherwise I'd go with gutloaded ghost shrimp or market prawns.
