I just had 2 of my small heaters die on me in a row while trying to use them for my betta tank. They were old and had been used for several years, so maybe it was their time. I went to 4 different places looking for a new heater and was appalled at the prices and crappy selection. The only brands I could find were Aquaeon, Tetra, and Top Fin. What happened to Visi-therm? My Visi-therm stealth has been running in first my 45g, then my 20 long, and now my 40 for about 4-5 years without a single problem and after price matching it from Bigalsonline.com it was only about $17. The smallest wattage heater I saw at any of the 4 stores I went to was a 25 watt for $17. That was a Top Fin heater, meant for a 5 gallon aquarium, and yet the tube itself was about 10" long and almost 2" diameter at its widest point. That's as long, and fatter than my Visi-therm stealth, and about 175 watts less power.
The Aquaeon ones were no better, just as long or longer, only slightly thinner, and even more expensive. 50 watts for $32.99 (on sale for $22.69), a 100 watt for $36.99 (on sale for $24.89) and so on.
I'm just appalled at the prices, and that they think a 10"+ heater can fit in a tank smaller than 5.5 gallons.
