Hello Lija! Just read your thread, very informative but at the same time sad. I really like these frogs and even found a probable source in U.S. But last thing I want is to get them and watch them wither and die.
Did you and Vet came to any conclusions about your frogs issues? To me it sounded like a very agressive opportunistic bacteriaattacked a stress weakened immune system. Some bacteria target the brain and nervous system and are highly lethal. That would explain the neurological symptoms and later skin lesions. Did Vet do autopsy on dead frogs to determine cause of death? Good luck with remaining one
