Sexing adult bullfrogs and other issues!

As long as the enclosure is big enough to hold both frogs and one is not significantly larger then the other, it should be no problem keeping them together.

Males have yellow throats and the tympanum or eardrum is larger than the eye. In the female the tympanum is about the same size as the eye.

I just noticed that you are from the UK. Before that, I assumed what you meant by bullfrog was the American bullfrog, Lithobates catesbeianus (formerly Rana catesbieana) when I wrote my response. If the bullfrog we are talking about is not Lithobates catesbeianus, then disregard my original response.

Kurt- when was their name changed to Lithobates?

Yeah, just when I think I have names figured out, a nice sharp kick to my hind-end is given to me. What happened to the genus Rana? Sorry, I can't spell none too good

Rana is still around, example Rana aurora is still Rana aurora. I believe, though I am not 100% sure, that it was Darrel Frost that changed it in 2006.
