Hi Paul

I haven't bred hongsloi so I'm not really qualified to 
answer this, just qualified guessing - the lateral band 
in rotpunkt is more zig-zagged than hongsloi who has 
a more even/solid band.

Norberti show the abdominal stripes caracteristic of
cacatuoides-group-species very early They also have a 
series of spots on the base of their dorsal fin which 
the agas lack. The lateral band of agassizii seems narrower 
than norberti, as well as sharper. If they are juveniles 
(>1") these distinctions should be quite clear.

You should be able to sex agas from 1-1.5 in TL.
