Thanks guys. That makes sense as in central PA is just dropped to cold and snowy from relatively warm for January only about a week ago. I think I will try an incandescent heat lamp. I found a Zilla Night Black Heat Incandescent Spot Bulb on Petco.com, but it only comes in 50W, 75W, and 100W. Since I have her in an 8L hemi tall, I am worried that these might be too strong wattage and make the tank too hot. I would have a regular light on a timer still for day time, so that the heat lamp can be on all the time as necessary. Right now the tank is hovering around 20C-22C (68F-71F), which image is too cold. She seemed to be shedding some skin too when I examined her last night. Or at least I think it was that. It was a white, a bit goopy, thing coming off her.

Would a 50W black heat incandescent spot lamp be appropriate for a GTF in an 8L hemi tall? My radiators are seriously old school and they are on/off only, no thermometer in the apartment. Maybe a ceramic bulb would best? Do they come in different powers? If so which would be appropriate?

Thanks so much guys!

Oops, I meant 8 Gallon tank, not 8 litres (I'm too metric!).
