OK, so we bought our tank off trade me, and It came with a fair number of breeding platties.
I'm not really a platty fulla so we bundled them all up and gave them to our local fish store.
Aside from two males that caught our eye, a big bright yellow fulla with a bright orange tail and a wee bright orange boy with a black tail.
Now I've heard that platties can change their sex, but I thought "Naw, It'll take ages, she'll be right for a while!" but a day latter I noticed the big orange and yellow boy chasing the other one around, but not aggressively, he seemed more attentive as if hoping for a bit of how's your father.
I'm pretty positive we sexed them correctly, we spent several days observing them all and the orange one held it's rear fin up all the time.
But now it's rear fin is fanned out and held down.
So is it possible for him to change sex so quickly?, or is it more likely we sexed him incorrectly?
Cheers guys.
