yes I've had Fu's for quite a while. I outlined the problem w/ these fish in the article. I've keep 2 for almost 4 yrs.
They are poor shippers, they tend to hide alot and they are one of the more troubling lions to wean over. So you have to make sure their eating well and happy. Both are difficult, but if you do get a healthy one and it does appear interested in food- you've got a good start.
Large bodied lions are easy- they wean over easy and they adapt easy, the smaller species are usually more difficult
