I have some young (born Nov. 1st) blue alleni, and it really seems to depend on each one's personality. I have been picking the bigger ones up to sex them, and have seen a wide range of behaviours.........all the way from "Bigg 'un" and "Gentle Giant" who are pretty meek and tame, to "AT aka the A Team's Mr. T", who was a holy terror with pincers, looking to take a piece outta anything within reach!
