Dracula goby lifespan?

[SlugSnorter]

I really like these fish and am strongly considering getting one, (yes I know their expensive and yes I know there's stuff that looks a bit similar at lower prices), but how long do they tend to live? anyone have experience with them?

I’ve always heard gobies usually fall in the range of 3 to 5 years. But then there are people who have had them for twice that.
