As I sat watching the larger male came out from behind his shelter under a rock and started beating on the smaller male. Got him away from the cave, then tried to get in there himself, but alas, the cave was too small for comfort so the larger male sulkingly went back to his hiding spot.
ok, I figured this man needs a bit of help, so I took one of LyreTails caves, which are quite a lot larger than the standard Zebra caves, and swapped one of the caves with this one.
I think it took 1 min and 34 seconds, and the larger male was well settled into the new larger cave, and is now leaving the smaller male alone.
The smaller male still can't believe his luck and is excpecting an attack any time
