yeah i was thinking it was a female but didn't wanna get your hopes up if you were after a male!! i got a 9" costa rican male too. nice and gold colouration for sure but personally i would rather a Nics variant. not sure if you can get em over here though
it was given to me as a female but its highly aggressive and territorial. i had to move it into the tank its in right now because its kept killing my tin foil barbs in my other 125g. sometimes the red dots show alot which makes me think its a male.
