I have 3 babies 1 male mojave, 1 female pastel and 1 spider. The male and pastel are about the same size 180g's but the spider is 220g. She is noticably bigger. The only one I have ever had grow faster than my spider girl is my mojave female. She is 750g and is only an 09 (and no I am not power feeding her) It is interesting to watch them as they grow.
