I have a 24 x 18 x 36 natural terrarium with a misting system. It houses 6.2 Red eyed tree frogs. I went to add more feeders to the tank tonight: hornworms, dubia, and crickets. One of my males came out and I noticed his eye is swollen and has some clear liquid coming out. (Photos attached) He can barely open his eye and uses his back leg to "force" it open. He then rubs it a few times like it itches and then he acts like he is fine. None of the others have any swelling. Do I need to separate this one or is it better to leave him in the tank he is used to?
What do I do?
