Sexing: males will have more color especially orange on cheeks and rays. Males will have a slender look to them. Females will be dull gray in color and darker body. Also will be rounder and fatter.
Breeding unknown (to me anyways)
Only know of one successful spawning in a aquarium it was in brackish water. All the wild spawnings i have found research on were brakish as well as farm breedings. I had a huge pair both over 14 inches female was swollen with eggs but would never lay the males genitalia would extend out with wierd looking appedages on it when he wanted to spawn. But female would never lay eggs mine were in freshwater. Pair in the pics are not mine just a reference photo. Also even though they can get huge (over 2 feet) they sexually mature at a very small size.
