thanks lymiq! yes. i got the female just over a year ago when toyin imported his first one, and then added the male a while later when he finally got more in. the male is not as aggressive an eater as the female. i didn't really keep track of the growth of the male, but the female has probably put on several inches. so its not really a lot, but noticeable. but whats more noticeable is the increase in girth...thats for sure...
