Advertisement Hello! My name is Kenneth for NoCal and I am a carnivorous plant guy, and now I guess I am hooked onto keeping insects now because of how easy they are to care for! So. My setup is a 10 gallon with 2 1/2 inch play sand with some paper roll tube hides and a few fake plastic plants. I read up here I need a heat lamp and eco earth mixed into the sand, is this true? Also my beetles are ‘itching’ their feet, it’s like they are trying to rub something off but there is nothing there(one corner of the tank is moist). Anyway, I only have 5 beetles in my 10 gallon tank. I have 2 blues(male and female), 1 black smooth Death feigner, 1 E. Obscurros, and 1 wooly. I am getting 5 more blues and 2 more smooths to lighten up the activity.
