What sex - no idea. At this early stage, I don't think even they know themselves But as far as the colours, I'll have a go. Top right, White butterfly, centre young blue diamond and on the left, young turquoise.
Thirty-five years keeping and breeding discus, and I'm still learning :P
Merrilyn, White butterfly don't look like that when young. Besides, white butterfly are a derivitive of pigeon strain. No bars, even over the eye. White butterfly juveniles look quite different from the adult fish. These are no white butterfly.
The fish in the foreground are young cobalt blues. They'll lose much of the striation on the body as they get older.
The one in the middle is without a doubt a blue diamond.
2nd pic confirms it. It's a Cobalt blue juvenile..... No snakeskin. Snakeskin juveniles at that size (From the pic my guess would be about 1.5" fish, not inclusive of tail), have hardly much colour and have 12-14 prominent bars on the body (as opposed to this fish which if stressed would have one prominent eye bar and 8 faint black bars on the body)
Good call Kev. I couldn't make out that first one from the pic. So there ya go tank, all identified. Now let's ask Kev if they should be wearing pink or blue booties
