Where did they go?

Leucistic Tank
Small tank
Well, it is a sure good thing that the axolotls were separated! The big tank now has four or five, maybe six, axolotls. The leucistics are hard to keep up with because they are still small and speedy, but I would estimate about ten now. The little tank has about three or four that I can see. All of them are small.The question now is why the axolotls remaining in the large tank are so large why the rest are so tiny comparatively. The immediate answer that comes to mind is cannibalism: eat the most, grow the most. However, there are no axolotls in the little tank where cannibalism has occurred with sizes comparable to the axolotls in the large tank. None of the leucistics have outstanding size either. Perhaps the size of the tank is a factor in the growth rate of the axolotls. Another potential food source is being experimented. Frozen beef liver cut in strips are eaten well by the larger axolotls, but not quite as readily by the small ones. It is also a great treat for the full-grown axolotls.
