Vern, At 1" they are a bit too small to develop their anterior dorsal fin extensions or lyretails. At this size you just might be able to recognize some males by a squared off back on the tail fin, however. A. juruensis & A. sp. aff. juruensis can be separated from other cacatuoides-complex species by having a lateral band that stops in front of a caudal peduncle spot.
