Not saying it is not possible but if you check polls you will see that maybe one out of 36 makes it to five years, and that is with hobbyist that have five plus years experience.
Most don't live long as the don't ship well. The consume them self to survive and are hard to bring back after they have started to expire.
Some are better than others. If you can get a clone your odds become much better. They are recommended for people that run reefs as they require the same care as SPS. Most inexperienced hobbyist don't know enough about them but buy them for their clown fish. That is why people always tell you they need MH light to keep alive as they need lots of light and need stable SG as they are sensitive to that as well. Never keep one lower than 1.024-1.025 if you don't they can't absorb the trace elements they need.
They need to be fed heavily as well and that does not go well in most nutrient poor environments.
The hobby has come a long way over the years, but we are still not sure as to what they need to survive ( for long term) maybe in a few more years.
The biggest problem I see is that most are taken from the wild and clown fish in the wild need them to survive as they are poor swimmers and easy prey for other fish.
