As with any fish I would make sure that it is eating at your LFS. Ask them to feed it, and make sure that it eats. I have no experience with this fish, but do have a couple that are considered hard to keep. Also find out what they feed it. It would be a good idea, if you purchase the fish, to get the same food that they are feeding it. You will have a better chance of getting it acclimated if you have the same food that they feed it.
