Thanks for this great reply
I'm not critising the temps recommended in care sheets or books, but do find this to be interesting and conflicting, as they did say that temps over 80F would cause stress but did not specify if this was anywhere or overall, but your point about the D3 from UVB is a good point, but the tube runs the entire length of tank, so the fact they chose to bask exacts under the lamp may go against this, as at least some amphibians have been known to see the UV gradients. you may be spot on with the fact that if the entire enclosure rises to that then may it be a problem, but this is something I was unsure about, but was considering. Some did say to provide a basking spot, though, and some don't, which is what makes me confused. I would definitely not go to the beach at that temp though, I'm tanned enough, but Scottish so I'm a weakling to heat, which makes us humans very different towards temperatures, as amphibians are in different locations. Truth is, it's not really a debate, but i'm looking for different opinions/advice, as I want to provide the best for these guys and also want to show people what experience I have had and see what others have, but this is Bombina variegata, not orientalis which may be different
