Im not sure he meant the website itself but the hobby of monsterfish keeping. Thats how I took it at least.
I feel your pain though. I hate when I'm browsing planetcatfish and find a cat that would be the perfect size for my tank and looks really good to boot, but no one has them. I'd love it if all the fish I wanted were farm bred so I could pick them up anywhere. On the other hand to continue the car analogy, I get a lot of looks in my Regal T type because you rarely ever see them. People comment and offer to buy it several times a week. Thats a nice ego boost I wouldn't get driving a vette that while nice people see every day.
