Ive had one before nice peaceful fish as others have said.Mine was a little skittish and reluctant to eat at first but it grew out of that pretty quick,few months and he'd eat shrimp right out of my hand.
They are very slow eaters- I feed mine in a corner where he waits at feeding time.
No body messes with him. They mimic moray eels when they feel threatened
They're also known as a Comet
I read somewhere that you can sex them by the size of their spots but can't remember which is which.
They are very shy at first and will spend most if the time in a cave they choose but once they're comfortable with you they come out and then you get to appreciate their beauty
