[Tank crash]

I lost a colony of cherry shrimp today, I had a tank set up in a different room from my fish room, my son go sick and I didn’t check it for 3 days, the pump must have died and the whole tank perished, I’m completely bummed out,

I’m trying to figure out what heater I want to use, my basement fish room in Illinois gets pretty cool, 65ish degrees, and I’ve had bad luck with incandescent bulbs.
