I own three Pacific Chorus Frog froglets. I have them in an 8 gallon vivarium with a screen cover. I've never seen them even go near the water. There is a few hundred springtails hopping arouns on the surface and they still won't go in. I was away for a few days and the water almost dried up, but still with dried skin they wouldn't go in the water. Tody the temperaturr was nearly 100 and they still wouldn't go in. I've heard of darts takinh rare dips and they aren't even pond frogs. Is there a reason they avoid it? I fill it up every week with distilled water. For what reasons have your darys tool a swim? Anythig I can do to coax them in?
