Re: Help sexing my cobalt blues
I can see why you're confused. They do seem to have mixed indicators. But I would say the larger frog on the left picture (the photo with both in it) is a female, the one on the right is probably a male. How old are they? If they aren't like 9-10ish months old (at least) it's still going to be hard to tell.
