Thank you everyone...we're very excited with our new family member.....some learning mistakes like buying a glass tank...but I'm handy and making it work until we decide on the new home.
Glass tanks are fine...as long as they are set up correctly. You may have to mist more but the can work just as well.
The 20g is fine, added foil to the top, CHL, foil wrapped the sides to help keep heat in....guess it was a little more than I was thinking would need to be done, but it is indeed "working". Def going pvc for the next tank.
