Wilfred,

My technical knowledge is not too great on such subjects 
but I have read that sperm can have difficulty penetrating 
eggs if the pH (or is harness the factor?) is not similar 
to the natural environment of the fish.

This is a beautiful fish and I hope to have them again soon 
as my friend has six fry he is growing.  They were spawned 
by someone from the North of England who seems to have 
success with most fish.  I believe though that the water 
from his area is soft.

Good luck,
Ken - Scotland.
