Shell mine dont do it all the time, just now and again and when i see them i take the pics maybe your just missing them doing it or there not settled in yet? dont worry too much as they will
I have a couple of females that like to position themselves tail first in a cave, I've also noticed the same behaviour in juvenile males. Perhaps they find it easier to defend the cave facing out.

Just a theory, but perhaps immature fish and females do this. Males sit "in-situ" with their heads in. I've noticed this behaviour on my pair of <i>Squaliforma</i>.
