Bangai Cardinal Laying down?

[carlson]

I recently bought a small captive bread bangai cardinal from live aquaria. Its been doing great ( as far as i know) and it's the biggest eater in the tank. It isn't getting picked on any except the occasional quick chase from the flame angel. Earlier today i saw it litteraly lay down on the bottom of the tank completely flat. At first i was worried but then i got right back up and kept smimming around. I saw it do it again later. I wonder if its tired or getting to much flow? I read that these fish can be harder to keep happy than they seem.
