Thank you!
The room this tank is in has two more tanks and 2 computers that run between 4 and 15 hours a day so even when not heated in spring and autumn it stays around 22° (71F) and is pretty stable.
Next question would be if that is too warm for the whiteclouds. I know they like colder water from the research I did, but numbers don't speak to me as muh as personal experience from other people.
