heater watts to tank size?

[ScuitoAmi150]

What is the highest watt heater you can have for a 1.5gallon tank? If it is an adjustable one and only for winter time use? (it stays chilly in the house during the winter)

I would go with a Hydor mini heater. I'm not sure of the wattage on those though.

I believe it is a 15watt? I was wondering, our local family run pet store has a tiny 25watt, with adjustable settings for $8

I have a 25 watt in a 2.5. It might be too big for a 1.5.

Oh. I probably won't get it then. I think I'm getting the Hydor mini for christmas. So I'll just give it to the fish who needs it. It is just chilly around here in winter, but both males are building bubblenest (and my female is attempting)
