Like joe said, if you are feeding something small and haven't moved him up, he is going to grow slower, i just moved my male from 2 adult mice to small rats and he has begun to put on weight like crazy, never mind a little bit of length. I have heard people say males grow slower and than females and such, i don't know for sure if this is true, but ya never know, some animals may convert food to weight while others convert it to length.
