Thank you all for your prompt reply I feel a lot better now As instructed on a Greek Forum for Reptiles, (i was on that before i found your forum!) I have put a frozen water bottle on the terra, and the temperature has dropped to 25 already. So, hopefully I will not see his little red eyes open today before night

It's very difficult to get a green eye here, we only get them from abroad, and they're very rare to find. I was thinking of getting a pair, however, there was no pair available! Could it also be that he/she (I have no idea of the sex yet) feels lonely or something? I know that frogs are a species that does create its own community or something, not a one person thing or so .. (please excuse my bad english.. it's rather early here and i just woke up!)

Have a great day everybody
