I've browsed the site and didn't seem to find an answer in the other posts, so hopefully I'm not re-asking something that's already been covered.
I bought another Dumpy a month or so after my first one had passed away. The new one, acted a worlds difference from the first (which wouldn't eat hardly at all, was brown, and stayed on the bottom of the cage all the time). This one stayed bright green to blue color, explored at night, slept high in the cage either on the vines or stuck to the class, and would eat as much and as often as you would allow it. The past few days he started staying in the water a lot, turning brown, refusing to eat, and over one night both his eyes become cloudy. After consulting a vet, they said it was a bacterial infection and there wasn't much I can do.
My question is...How does this infection happen and how can I prevent it from happening to another frog?
If it's a question of cleanliness, I spot clean every few days or as often as I see anything, I change the water dish every night, and I do a full cleaning of the tank every 2-3 weeks. I was worried about if I was keeping the humidity too high (it stays steady around 70-80%), keeping the environment to damp, or even if my substrate(T-Rex Jungle Bed Premium Blend Forest) is causing the issue. Any input would be appreciated, thanks.
