Yea, I think I would have noticed that... Lol. My White's is male and on the small end of the scale, whereas my RETF is female and on the larger end of the scale. Side by side the RETF is about 2/3 the size of the Whites in length snout to vent. Now, my understanding is that any frog will eat any other frog, some more apt to do so than others, and a frog doesn't have to be larger to eat another frog, just hungry. BUT, they're very well fed and I watch them at night and I haven't seen anything disconcerting. Like I said, I actually take my herps to the vet for check-ups, which in my experience most herp owners don't regularly do, and if two different vets have told me that they're healthy and happy than I'm not stressing about it. I have plans for new enclosures, separating the frogs to give my RETF a more arboreal enclosure (those cylinder towers) and expand my RETF collection with some color variants/albinos at that time (leaving the White's in his own enclosure or maybe getting him a girlfriend). In the meantime, I keep a very close eye on them and haven't witnessed anything concerning.
