I have never housed Chondro's in aquariums so im not much help, But RHP's are your best bet with a glass tank, just a thought. However i think alot of info your looking for could be found in "the more complete chondro" by greg maxwell, read it twice. As far as humidity, the method i use is dew point temperature (greg shroeder is the man), and my one and only neo i just keep his paper towels wet (6qt tub). Temps, high of 88 - 79(gradient), night time low 82 -79 its some times lower depending on what florida weather feels like doing
