Is this a male or femal cockatoo?

[dodgefreak8]

hey everyon I seem to have a cockaoo that doesn't know what sex it preffers. It has some male markings and no black lines on it lower fins but it hasn't gotten it high dorsal fin and is very light on the coloring. also its stopped growing and never flares at males or females.

the fish in question is to the bottom right.

I would say its a female..

it looks like a female to me

I agree, it probably is a female. The highly bred (& inbred) color forms of this species has produced many masculine features on females of this species. I sometimes wonder if the problems some people have with this strain has something to do with 'masculinization' of the females.

I disagree. I believe this is a typical male with repressed development because of the presence of other males. I suspect that given a tank to itself it would soon develop into an undisputable male.

I just read about that. i am going to put him in my 29 and see what happens.

It looks more like a young/small male to me.

Does it ever turn yellowish and do the ventral fins show more black than the obvious males?

 

[Zapisto]

it a young male for me also, dominate young male.

thats just it. it has never tried to breed(turn yellow) and there is no black on its lower fins. I got this fish with all my others and it has stayed the same size as my females. I moved it so we will se what happens.
