Too many mealies?

[MartinW]

Is it possible to have too many mealies together? Will they start eating each other? Will the beetles eventually stop laying eggs if there are too many mealies? I'd like it if it's not a problem, not because I need all the mealies, just because I'm greedy, and so I won't have to seperate them all the time. Also, do mealies and beetles always eat the aliens? How important is it to seperate the aliens from the others until they turn into beetles? I have tons of mealies so it's almost impossible for an alien to live in there without encoutering a lot of mealies, or even a lot of beetles.
