An ISO is an isolation tank. This is to just make sure she is not sick and to get use to the new environment.
It is a small 10 gallon set up the same as my main tank. Right now the humidity is real low as that was her (Evvy) environment. (and fed commercial food as well

)
I will slowly bring the humidity up to what my main tank is, then after a salt water bath, she will go in the main tank.
I was surprised at how friendly she was. Right now she is climbing over everything checking it out.
