10" Gorillus Black Umbee Male or Female?

  • We are currently upgrading MFK. thanks! -neo
Looks like a female to me, but it still has some growing to do, so could just be an immature male. I'd guess 70/30 female.
He she is 1.5 years old..So aggresive for another fish.Kill and eat 7 fish.When i put mirror front of it showed yellow and black bar colour and red eyes
 
Females aren't bad. Not sure if it will reach 15" but maybe it could with a good diet, less than 20ppm nitrates in the water (through water changes), big enough tank (~680L), and no breeding.
