Strangely, they don't seem to be the smallest fish. They are average or
a little above average. This is why I was wondering if it were the
bigger males killing the smaller males. I'm hopeless at estimating size
but I think they are about three cm long. The biggest ones may be 4 cm
and are just getting a touch of blue on their anal fins.

I added a heap of new rocks and stuff to the tank and I think this has
reduced the problem.

The first few all had their heads eaten off. I have saved a couple with
their tails eaten off and dumped them into a tank with smaller fry.

could be but unusual at that small size.
I'd increase frequency of feeding, lower the temp a bit and either add more
ornaments or remove them all.
That should chill them out a bit!!
Beware of baby electric blues eating other fry too!
Until you see one make a kill treat it all as suspicious, test the water for
ammonia and nitrite.
Chuck some shellgrit or coral or marble or something in incase pH
crash......
hmmm I dunno...... But I imagine it's all in hand mate.
Play the numbers, sometimes the weak just die.
life goes on.
