Ok so I have a 20 long tank that I'm currently maintaining and ambient temp of 82 with surface temps of 86ish. I do have a uth that I'm not using till my new thermostat gets here
But my main question is on the issue of belly heat and their need to regulate their body temp. Some folks say if the general temp is good belly heat isn't needed. Some say it is. But it seems to me if they need to be able to regulate their temps then they need a cool end and a hot spot rather than just a general temp. Also stick with the size uth recommend for the tank or go bigger? My current uth is for a 30/40 so it takes up about half of my 20L tank. I will be using a thermostat. Thanks for your advice!
