i had one, lasted 6 months or so. seemed to be doing well, eating then died.
he was eating frozen but you had to get the food down to him, he wouldn't come up and eat with tank mates. a nice fish but made a mess with the sand, i don't think i would get another because of that and a pain to feed it.
i also read they like colder water as mentioned, and don't do well in the long run.
