I've had a Spotted Drum for 15 months. Several pictures of it taken shortly after I brought it home are on my personal profile. I don't think I've ever seen one in a dealer's or wholesaler's tanks, though on-line sites occasionally list them. It's a beautiful, wonderful fish, a delight for divers who see them on the reef.
This is the second one I've had. The first lived for 7 years, I lost it when it jumped out of a partially uncovered aquarium. My fault. I find them very easy to keep, willing to eat almost anything. The problem is they don't travel well in the tiny space commercial shippers allocate to fishes. I hand caught my Spotted Drum (Equetes punctatus) off the Caribbean coast of Central America, and shipped it home in quadrupled box bags with more than a gallon of water, in a cooler chest fitted inside a nylon check-through suitcase. I know Customs inspected the cooler because they drilled holes in it , presumably looking for drugs. They did not disturb the fish, and reclosed everything properly. The required Fish and Wildlife form was attached to the cooler.
This kind of extravagant care and swimming room is not commercially feasable, but it's what is needed to successfully ship these fish.
