I have one, I don't like to talk about it openly anymore because it is still one of those fish that many hobbyists believe should not be kept in the home aquarium and those of us that do keep them often get flamed for it.
Matt Pederson has some great articles/hints on these guys, but and this is not to take away from his work at all, I personally think he can be a little obnoxious, especially if you start to have trouble with one.
I've had luck weaning one, and one was partially weaned when I got it. If you can find one that is already weaned (which is darn near impossible in most cases), definitely go that route. I try not to buy a specimen that hasn't been in a store for that long, if it's fresh into the hobby, it will definitely need to be weaned. The ones that haven't been in the hobby for long are usually the specimens that look the best though.
My best suggestion/advice is that you have to have A TON of patience with these guys and you must be able to observe them, and observe them often. They don't like anything less than near perfect parameters either. I was literally doing 1-2 cup water changes daily, if not twice a day when my female was in my 14G.
