Update 13/11/11:
As of last night there are 25 fry still alive, and I guess I lost about that many in the last week. They seem like hard little critters to keep alive.
Also as of last night the male Cran's bully is guarding another clutch of eggs, and is today trying to entice yet another female in to his man cave.
[Edit] Photos of them spawning (sorry about the distortion, photographed at ~50+ deg through 10mm of glass):
[Edit 2] A pic of the second spawn that only a very few hatched from, most died without dad looking after them:
