I have a 1.3. When I got them the male was about 40g, he was 65 last time I checked.

One female, brown wild type looking was about 30, she was 48 last time I check. She doesnt seem pregnant either.

The last female is white with black dots in the back and a black hood. She was about 30 too when I got her. She was 37 last time I checked.

But I dont think their weights have nothing to do with their color. The pied seems to be alot more shy than the others, and I see her in the wheel and eating less than the other 2. On top of that, because of her low weight, she seems to be getting dominated by the other female.

Just my observations
