I also think the ACF is in danger of losing a limb or two to the axolotl. I have kept and bred both species. Axolotls have a type of "teeth" - they have ridges in their gums used to tear off junks of food. Axolotls have been known to latch onto another axolotls arm during feeding time and rip it off. Not often, but it does happen and it is rarely an intentional act of aggression. Axolotls have regenerating capabilities, ACF do not.
