i would like to start off by saying im not too knowledgeable with this species so if im wrong i apologize.

i would seperate the frogs. frogs do eat other frogs in the wild.

if the marks are bad, you might be able to apply neosporin WITHOUT PAIN RELIVER. research that ahead of time since im not familiar with your species. or maybe someone else will chime up.

whats the size difference between the frogs? if the smaller one is getting bullied maybe wait til it gets bigger then try putting them together again.
