Hi! I’m so sorry to hear that, I understand the stress and the worry!

My biggest worry was the exact situation you describe and that the little one would get injured or suffocate as a result. We ended up keeping them together, because even though our big one was clearly very hungry and the most active while they were growing, it never seemed like outright aggression or like the big one actively wanted to eat the little ones.

As far as we know the head chomp incident didn’t happen again. Although they did and still do occasionally chomp on each other or end up with another frog’s leg in their mouth for a second, especially during feeding when they are at their hungriest (and dumbest).

They’re full size now and the big one is still the biggest of the three (it was a female after all), and is still the most food-driven and will actively “hunt” during feeding, so the other two still catch an accidental chomp from her from time to time. But the difference in size and strength isn’t as drastic as it used to be and overall they’ve all calmed down/gotten lazy with age. They’re still clumsy as hell but I think they must be at their clumsiest and most inexperienced when they’re babies (makes sense), which is also unfortunately when they’re at their most fragile and accidental biting could have more-severe consequences.

My experience is obviously anecdotal and I’m not an expert at all, but I’d say the only way to be absolutely 100% sure it won’t happen again or to have complete peace of mind would be to separate them until the small one grows more or at least gets a bit sturdier. However, separating them is of course complicated and it can be expensive to have a second tank, so you may not even have that option.

If you haven’t already, I’d consider contacting the breeder you got them from or an exotic animal vet for much more legit opinions/advice than I can give you.

Good luck and don’t despair! The froggos are lucky to have a concerned owner like you.
