i have a tank setup now with six fbt , one japanese fbn and one chinese fbn and have never had a problem. more often than not the newts will bite the toads feet on accident when trying to get some food, but that doesn't effect either one. if you do your setup properly and keep your amphibs fed and healthy then you should no problems. i also woulkd like to know how big the of a firebely toad the other person has that it ate a fiebelly newt, even the chinses are not that small unless you get a baby.
