Black Occy (Lamprologus speciosus)

Very difficult to sex visually. Once the Alpha male has been established, sub dominant males can often act like a female. Mature males are larger than females

Juveniles : Males grow faster and the lips look bigger and thicker. This can be noticed around 3-3.5cm (1.2-1.4") mark.
Sub-Adults : Females are much more aggressive. When a shell has been chosen, she would never leave that site while the males will often wonder around the tank.
Females will also turn half orange/yellow (front half of the body) when fighting amongst females and when they are sexually active.
Males can do this but rarely. The colouration isn't as intense as the female and would only be for a few seconds.

Generally an adults will attain the following size.

Males around 6cm (2.4")
Females around 4.5cm (1.8")

These shelldwelling Cichlids display conspecific aggression which is extremely high amongst females. Contrary to popular belief, they are relatively peaceful towards other tank mates, however they will defend their territories aggressively.
