I have owned red eyes for almost 5 years. I never just strictly fed them waxworms I would offer them 1 or 2 a week as a treat until my supply was gone and then I wouldn't get more wax worms for several months sometimes longer. Crickets I tong feed them 2 or 3 each once week and maybe another 1 mid week I don't really have a schedule. How do you know how many each of yours are eating if you just let them help themselves? One of them could be eating the majority and the others just get one or two. And the whole eye situation was just a warning to you I'm not saying it's going to happen, I'm just giving you a heads up, like I said the frog is probably over 5 years old and this happened over a long period of time, she starting showing sign of the eye problem over a year ago. It doesn't affect their general health or anything it's just has cloudy vision is one eye.
