Hi there. I've had two fire bellied toads since last November, and recently noticed that the one seems to occasionally bite the other one. This usually happens when I'm about to feed them - the one toad seems to get really excited, and sometimes chomps down on the other one. The toad being bitten seems somewhat sick, and I wonder if this could be stress-related.

Is this normal behaviour for these toads? I am going to separate them for the time being, but if anyone has any suggestions, please let me know.

Thanks!
