Welcome to the forum!
This frog is closely related to species in the genus Telmatobufo. There isn't much written about their captive care; one source I found recommends the temperature between 72-78 (F).
Cloudy eyes usually indicate an illness or injury. As far as I know there is no easy treatment and a visit to the vet is probably the only choice. I have heard that older frogs develop catarachts and sometimes eyes will cloud up just before skin shedding.
Note: I found this bit of curiosity on a German pipidae site (http://www.pipidae.net/faq_illness.php):
"A German pipid frog keeper told me that her frogs lost the cloudy eyes after treatment with Rabomed from Hobby Dohse. She actually wanted to treat her fish for another illness."
Good luck with your frog![]()
