My guess is exactly the same as ricky. Fish number 4 gave me a bit of trouble but in the end I couldn't really find anything definitly male about it so put it as female.My best guess is
m
f
m
f
m
m
But like was said they do need conditioning as none are gravid plus some look a bit young still??
cheers

in different bloodlines head shape goes out the window... seen males with pointy noses and females with blunt noses... females so hairy you'd think they were italian males...Head shape usually is like a triangle. Draw a triangle, then cut the top peak off and draw a line across from side to side like a spade. Thats usually male.
Females cut the top off and draw an arced bit from side to side like a semi circle top side.
Females can also have quite a rounded head altogether with no real straight sides.
