Those are both really good pics of a fairly active fish...
I'm assuming they do the whole dart forward a bit, pause, dart forward again, turn, pause, etc., etc.....cichlid swimming.
It's tough to time it so you click that button during the exact moment of the pause, eh? (esp. for no-flash pics) My shoulders have gotten sore doing this! (I think I need a tripod or something, lol).
Very nice colors on that fish of yours!
I'd like to see similar pics of your 'sub-dom male' now too...I'm curious to get a closer look and see how 'he' or 'she' compares to the dominant male.
