Advertisement I'm a terrible owner, I've killed the first invert I got. Nemo was Damon diadema who I got as an adult. She was very active and ate a lot. I started college and moved into a dorm where I should've been able to regulate the temperature as we do have a thermostat in the room that I kept set to 75 degrees, but it always felt colder. I bought another thermometer to check and it said the room was at 68 degrees. I coulda bought heat source for her, but I didn't and now she's dead.
