Does anyone know the history of blue vs green nannacara anomala?

[anewbie]

I've had both blue and green form n anomala but every green form i've seen has been 1.5x larger than the blue form - i'm not sure if this size difference is due to how the domestic are being bred or if this is a characteristic of them in the wild hence the question.

(this size difference is in reference to the male as the females are nearly the same size); the green form i had was hobby bred the blue form unknown but likely domestic.

In the 1980's I had blue, green and black (dark grey actually) and all were wild caught. Females all appeared the same. All the males grew to the same size, about 3"/7,5cm. The size difference that anewbie saw was probably difference in age and care,

I suspect the domestic blue has been runtified as i've not seen a large one. Oh well nice fish - one day i'll get a nice pair.
