Extremely secretive, difficult to get to eat (usually only take live foods like ghost shrimp, sometimes not even that). Its shy behavior compounds feeding difficulties. However, that doesn't mean that they are impossible. There was one particular case where we got one in at the store that did eat. The customer still has it (never sees it) after 2.5 years and it is still growing and doing well when he does see it. I would see if you can one that eats ahead of time, if possible.
