I'll see if I can get him into the herp vet on Monday.

ACK! I read that as "the bacterial infection kills forgs" not "tetracycline kills frogs". I hope this won't kill him. I did a very throrough cage clean yesterday, it was due for one but was nowhere as dirty as other showcase vivariuums I've seen in stores (I've seen ones with mushrooms growing inside and even one that had become overrun with centipedes!).
