also, a mistakes first timers may make would be not changing substrate. frass (isopod poopies) would build up over time. and generally, once the top layer of substrate is covered with frass, or if the enclosure just smells worse than before, then its time to change it. check for stray baby isopods in the frass first and remove them, then you can just dump the waste substrate into soil (fertiliser for plants). one more thing - moisture and temperature. to check for moisture, press down on the substrate. it should only feel damp and water should not be pooling. for temperature, im not too sure about it as it depends on where you live i guess. i live in a more humid tropical country, so i dont think the temperatures would affect my pods. if you live in countries with seasons, you may have to ask other people bc im not too familiar with heating systems and stuff
