 Temp fluctuation
I set up my 30g in the summer, so I haven't needed a heater yet, but the water temperature does change by about 5 degrees between day and night. Does this stress the fish? I've wondered if its something natural in the wild, but tank with heaters generally keep the temperature constant.
