Looking at the table on the back of the package, it indicates that the 25-watt heater is good for up to 8 gallons (iirc) and the 50-watt heater is good for up to 15 gallons (iirc). The store did not have any 25-watt heaters in stock.
So here's my question:
Will a 50-watt heater be too big in a small 2 gallon tank?
(making it overheat or something? be too hot? ... another thought just occurred to me, I should have made a note of how tall the 50-watt heater was to see whether it will fit in my tank)
I'm thinking it might be safer to get the 25-watt heater.
I checked the brand (before throwing away the package) and it was a top-fin heater. It was about $18 at my petsmart... they had "stealth" heaters that were more like the price on the one you saw (and stealth heaters are indeed all black). They had the 25 watt top fin too, but it was only $1 cheaper, and I wanted a heater that I could move to the 10 gallon tank later.
If I had no plans of going bigger than the 5 gallons I probably would have gone with the 25 watt, but the 50 watt is in there right now and seems to be doing a pretty good job. It takes up most of the back of the tank (it's set diagonally) but the 25watt wasn't much shorter.
