Behavior differences

Hi there.
Well we now have two axolotls and they both seem to have settled in nicely. We got them from the same place and they are about the same size but they act very differently. I think they're both females. One is a natural colour, is fairly active, likes to float around in the plants and doesn't really like earthworms but loves frozen bloodworms (messy) or beefheart (unnatural). The other is an Axanthic albino (I think), is less active, likes to hang out near the bottom or hide in a little cave, but is an absolute pig and will eat anything that comes it's way. It's halfway through regrowing a back leg which may explain the appetite? They seem to get along ok, the albino even seems to be affectionate towards the natural one at times.
Just wondering if anyone else has noticed different behaviours between different colours or sexes?

I dont think the colour has anything to do with behaviour,
after all us humans are all different, and if you think about most creatures in the animal kingdom they all have different traits.

I agree with Frances.
Its just nature, life would be pretty boring if we were all the same.
