Appreciate the responses.

You guys think fish and amphibians share the same parasites? I'm really reluctant to take him Back as its a bit of a drive, so I'm more willing to change the tank setup. I also really like the little guy, much more than my mudskippers anyway.

I can always drop the water about an inch above the substrate, but my guess is humidity will still be in the 70-80 range.

the humidity in my house is 55 ( I live in Houston and have multiple fish tanks.) so no idea what to do.

Has anyone else kept them in a wet enclosure before? Dart frogs are probably a better bet though eh?

Thanks again!
