I have several young black bullheads (not enough for a herd, maybe a covey
of bullheads - How's that Casper?) that rarely sit still long enough to
stand on their tails. These guys are the most fun to watch. They do seem
to engage in play behavior with each other as they appear to play a fishy
game of tag as one hides until another happens by and then gets pounced

As I think about it, I guess that tail standing could be a defense mechanism
though. Especially if it is in an area with vegetation. It would probably
be analagous to the screech owl which will make itself as tall and slender
as possible while remaining motionless so that it looks like nothing more
than a lichen covered stub of a branch.

BTW, when are you coming down to visit again? Charles moved back to Fort
Worth and the canoes are always ready!!
